Sponsored Grow: KIND LED K5 XL1000 With Ace Seeds In High Brix Soil

[Neiko]

You shouldn't be seeing magnesium deficiencies with those genetics. It's coming back to me now, when I ran the XL750 I too noticed an increase demand for magnesium. I used the way ahead (old snake oil) a lot it seems. Since I've gone to the white LED's I haven't used snake oil once. I've run both those strains and they performed very well without any "extra" attention. I don't know how true it is but I do remember LED discussions saying the lights create a greater demand for Magnesium. Are you seeing the red streaks up the stalks? I don't really notice that in the pics.

I do believe there's a higher demand for Mag with LED's and there's also an increased demand for Mag during the stretch, which they just came out of. But, although this is my first run with the XL1000, I've been growing exclusively with LED's for 10 years and I don't see any purpling of the stalks or any yellowing between the veins of the leaves, which would indicate the Mag def to me.

I do, very clearly, see some tacoing of the leaves, but, it's my understanding that this is the plants natural reaction to too much light. It actually closes the leaves to reduce the amount of light hitting the tops. Tacoing can also be caused by a fan blowing directly on the plant, but that isn't the case here.

Based on KIND's recommendation early in this grow, however, I've been running temps of about 84* F in the tent. In previous runs, I would start panicking if temps hit 80* F, but the tech at KIND, who is very knowledgeable, said 84* would optimize photosynthesis.

Things were pretty OK until the last few days (end of stretch) when this things started growing closer to the lights. Ideally, I'd have at least 18" between the lights and any colas. I now have cola tops literally within 6" of the lights.

I've been here before with other LED's and, worst case, just got a little bleaching on the tops of the buds:

I'm expecting a little of the same on this round.

Mornin Krip...im sure u will agree my plants are getting the max light they can in my grow room and i have NO tacoing because of it.
I never get tacoing because of too much light or too windy ......it comes from Mg shortages.....

I actually checked the plants 15 minutes ago, just after lights on. There's no visible tacoing right now. As the light increases in intensity and the heat starts to build up in the tent, you see it later in the day.

If the plants had purple stems or I was seeing some chlorosis between the leaf veins, I would think Mag, but I really believe this is due to light.

 

[Mr. Krip]

my plants are getting the max light they can in my grow room and i have NO tacoing

It's not the amount of light, it's the distance to the lights/heat. Here's an article on Cannabis light burn and I've highlighted a couple of lines:

Light Burn
Updated Dec 07, 2018
Problem: Your cannabis plant can only withstand a certain amount of light. After a certain point, your cannabis will start turning yellow or otherwise exhibit signs of stress on the leaves near the sources of light and/or heat.
How far away do I keep grow lights from my plants?
Light burn usually causes yellow leaves at the top of the plant directly under the grow lights (though it can appear on older leaves that have been exposed for a long time).

Sometimes the first sign a plant is getting too much light is all the leaves start pointing up, like this (though sometimes you don’t see any symptoms until the yellowing starts)

With light burn, often the inside veins stay green. Yellow leaves won’t fall off or be plucked off easily, unlike a nitrogen deficiency where leaves fall off on their own.

The leaves closest to the light may appear much more pale than the rest of the plant, and tips may turn yellow.

Another example of yellow tips from light burn

Sometimes light burn causes edges of leaves to turn up. If it goes on a long time, the leaves also start to become crispy and can even break off if you try to bend them

You may noticed just the tallest colas getting droopy, which is sometimes a sign the light is too intense (though it could also be caused by root problems or over/under watering)

Light burn is often mistaken for a Nitrogen deficiency which makes wilting yellow leaves. Nitrogen-deficient leaves fall off on their own, while light-burned leaves are hard to pluck off. A nitrogen deficiency starts from the bottom of the plant and moves up, while light burn often is worse at the top of the plant.
Cannabis light burn usually affects the top leaves closest to the grow light

A Nitrogen deficiency creates yellow leaves at the bottom of the plant as the Nitrogen is sucked out of the oldest leaves to feed the top of the plant. On the other hand, light burn produces yellow leaves at the top of the plant under the grow lights because the leaves have worked too hard and/or too long from the light being too close. The leaves aren’t able to keep up with regular plant processes.
Imagine sitting outside all day under a scorching sun, possibly for days on end. Even if you could handle it for a day or two, it might wear you down over days or weeks.
How can there be too much light if there’s no heat? Read the full guide
It’s probably light burn if mostly just the leaves closest to the lights are turning yellow

With cannabis plants that have light burn, your leaves can sometimes become yellow or red/purple, possibly with brown spotting, often with burnt tips/edges and margins that stay green. Other problems, like nutrient problems, can trigger or make the symptoms of light burn a lot worse. Leaves may also appear generally burnt in places when there’s too much light, especially when combined with heat or nutrient problems.
Nutrient deficiencies make light burn worse!
If you see light bleaching and unhealthy discoloration only on the parts of the plant directly under your grow light, or only on older leaves that are exposed to the light, it often means it’s too bright for your plants and you should move your grow lights further away! If your plant is also having other problems, it is much more likely to be affected by light burn. A healthy plant can withstand higher light levels than a sick plant.
If the lights are only slightly too close, maybe just an inch or a few cm, the yellowing from light burn may happen slowly over the course of days (or even weeks!) because leaves are dying early instead of immediately. Because of that, light burn may first appear on somewhat older leaves, which can be confusing and make it hard to diagnose.

This cannabis seedling is being burned by too-close LED grow lights

These leaves of this LED-burnt plant started curling upwards

This cannabis seedling basically grew up into the grow light! The heat from the bulb caused massive burning everywhere it touched. If a plant’s leaves directly touches the lights, it leaves “burns” from the heat of the bulbs.

This plant was green and healthy through the vegetative stage under an LED grow light, but the leaves started dying soon after flowering started (even though that distance had been fine in the vegetative stage). The reason was the LED was too close. This is also very common with LED grow lights with just read and blue diodes, without any diodes in the green spectrum.

These plants seem apparently healthy, but the top leaves keep getting lighter and lighter, in this case from a 600W HPS that was kept just under a foot (30cm) away. The leaves slowly turned yellow over the course of a few weeks, getting light burn even though the temperature was a comfortable 75°F (24°C).

These yellow leaves were caused by an LED grow light that was too close. If you don’t realize it’s light burn, the symptoms are inexplicable!

A mild case of marijuana light burn is often mistaken for a nutrient deficiency or a pH problem, but if you look closely, the symptoms are concentrated directly under the grow light.

Light Bleached Cannabis Buds Sometimes Turn White
This is how you get “albino” or white buds. Light bleaching is most common with high-power LEDs and HPS grow lights because these can be brighter than the sun. Basically, bud bleaching is what happens when buds get too much light, kinda like how hair can get bleached if you spend plenty of time in the sun. Except a “sun-burnt” bud is often less potent, and may have lost it’s “cannabis” smell!

Buds which have been bleached tend to be low potency or even have no potency (no available THC or other cannabinoids). Therefore you should avoid light-bleaching your plants at all costs!

Sometimes light-bleached cannabis will get mis-labeled as “albino cannabis” or “white cannabis” but the truth is that the white color is not healthy, so this is not a desirable trait (even if it looks pretty cool).
Most of the Time, Light-Burned Buds Appear Burnt
Often though, light burned buds look like they’ve been burned.
LED-burnt cannabis buds – notice how all the tiny “sugar leaves” have turned yellow or brown

In this case the LED-burn caused the leaves closest to the LED to turn red. Although the buds smoked pretty well anyway, they definitely weren’t as pretty as they could have been!

The leaves too close to the LED grow light turned yellow and wilted. For some reason, cannabis plants seem a lot more prone to light burn after they start flowering.

Another example of a bud that has light burn from a too-close LED

Light burned bud on top, healthy bud below

Solution: If your marijuana plants are getting too much light, try removing some of the lights or moving your grow lights further away from the tops of the plants. If you can’t move the light further away, bend your plants over so the tops are further away or if your plant is still in the vegetative stage you might even consider cutting off the top of the plant to remove some of that height.
Reduce power of grow lights and/or move them further away from your plant
(How far away do I keep grow lights from my plants?)
It is unlikely for your plants to get “light-burned” from the sun when growing outdoors, and they definitely can’t accidentally grow into the sun. Outdoor plants can show signs of light stress if plants were used to shady conditions and moved into direct sunlight without time to get accustomed to the brigher light levels. It also may be possible in extreme high light conditions if the plant is unprotected but in general cannabis plants like a lot of light.
When making changes to your plant’s environment, it’s best to make changes relatively slowly if possible. For example when moving a cannabis plant from indoors or outdoors you might consider giving the plant some shade for a few days before moving it into full sunlight.
Sometimes heat stress can look like light stress. When learning how to grow cannabis, it’s best to try to keep things at a comfortable temperature at all times for optimal growth. If it’s too hot for you, it’s probably too hot for your plants. Outdoors, it’s a lot harder to control temperature, but there are steps you can take to protect your outdoor plants from the heat including supplementing with sea kelp, partially covering them and making sure they’re well watered.

Thanks Krip...a good read.

 

[MrSauga]

A very good read indeed.

 

[Slowpuffer]

These guys with Doc's gear all have that look...either the soil is really, really good or they're using pics of fake plants.

If the leaves show mag def, then just go buy some new fake ones ? Problem solved !!

DAY #22/#14 OF 12/12

It's been a full three weeks of 12/12 for the original Orient Express and three Bubba Kush, and 13 days for the Platinum Cake.

The PCake should be just about done with stretch and did get most of her colas above the trellis netting a decent distance, but is really dwarfed by the other monsters.

Here are a few shots of the Platinum Cake which is now hooked up with the high brix soil and doing great:

I started the lollipopping today but have more to do over the weekend. I also made some adjustments in terms of raising the light as high as it would go, increased the fan speed to 60%, and re-positioned the oscillating fans to blow up through the canopy and blow some of the heat away from the plants.

And, just in case Brother Duggan was correct about the Mag def, I gave them a transplant drench with some Epsoms.

Hopefully, that reduces, if not eliminates, the leaf curl.

Finally, I hope everyone has a great holiday weekend and takes a moment to remember our fallen vets!

Much respect to those that serve to keep us free!

Happy Harvests!

Things are looking mighty fine bud!

 

[Duggan]

Yes they are eh Yeti......Evenin to ya Krip. Things are lookin a lil 'brixy' over here. Yes, ive given mine epsoms twice now. Prolly one , maybe two more times before harvest. Really helps ...cheers man!

 

[Neiko]

The plants are looking very healthy Krip. I love the looks of the Bubba Hash's. The smells that will be showing up on those will leave your mouth watering I'm sure.

Yeah, my apologies! There are currently three Bubba HASH, one Orient Express and an IHG Platinum Cake. I'm not sure why I keep referring to the Bubba Hash as BBK's?

I picked up the BBH's on the recommendation of Brother Neiko as a possible strain to help my Dad's pain and, while I haven't tried any yet, I'm sure impressed with the vigor, huge fan leaves, thick colas, and nice bud stacking.

 

[Mr. Krip]

QUICK UPDATE

I got a lot done today and now I need a shower and I'm too tired to start taking pics, so they'll have to wait till tomorrow!

Among other things, I finished cleaning up the lower growth and, along the way, I took out a bunch of weaker colas, some of which were close to 4' tall but just weren't sturdy enough to support any real weight.

by the time I was done, I had a 5 gallon bucket PACKED and, looking at the top of the canopy, you can't even tell anything was done!

Hopefully, with the combination of a little more room to fill out and the plant only needing to focus on developing the thick colas, they're able to put on some good weight, now!

Happy Harvests!

[Reave]

Looking good.

Are you seeing the red streaks up the stalks?

My plants have had these purple streaks at times. I feed quite a bit of cal mag. Guess I need to up it more.
