Severe tacoing need your urgent support

[Longhini]

shall i wash down the leaves with plain unph'd drinking water, its been 2 days since last foliar feed with epsom salt?

Seems unlikely as your a/c is in the room the tent is in (as opposed to being in the tent), but is any of that 15°F to 20°F (at a guess) cooler air from the a/c vents hitting the plants directly?

Nope. Window A/c blowing towards a 10” table fan (5 ft away) used as an inline fan placed at the bottom and blowing through an 8” duct into the tent. The duct end is at the floor of the tent blowing towards a corner where there is a 6” oschilating fan moving air around. The different between room temp and tent is 3 deg celcius during day and 1 deg celcius during night.

I just recalled an incident that occurred when all of taco leaves were present
I was running MH (dimmed to 200) in the 1st week and it failed and had to change it to hps and a week later the replacement MH arrived and I switched back to it without adjusting the height , do u think that could be the reason ?

First line of the first post:

An update, having those yellow dots appearing on my leaves , ! Can u plz help

 

[Tead]

Very nice recovery there Longhini! The lighter colored new growth fading to the darker green.... exactly what I like to see.
Damage early on is easy to grow past... no worries.

 

[natureman]

sprayed it with water+Magnesium Sulphate PH was 7.00 without any PHing , water source is bottled drinking water (low sodium) , lets hope i finally get to say they perked up after feeding lol

Your PH is too high.
It should be around 6.5 to 5.5.

Even with foliar spray ?

 

[bluter]

yes

 

[Longhini]

Plz help the issue escalated yellow dots turned brown and eating my leaves could it be because of droplets on leaves a slight or am I having a mold and fungus ? Help plzz

Looks like older damage growing out naturally. They get bigger as the leaves get bigger.
Be sure to get your PH in range... it's step one really. I do hydro at 5.5, but soil gets 6.4.

My watering Ph is always between 6.3-6.5 but my soil PH is what I’m not sure , I need advise on measuring soilph and flush technique ? Thanks you guys for continuous support , ur the god fathers of my babies

I need advise on measuring soilph

From Hanna Instruments' Website:

Slurry pH Testing

The slurry method allows you to get a representative sample and measurement of an entire area with just one test. Because soil pH can vary within a small area, be sure to take a representative sample. The soil should be taken from the same depth below the surface each time you test.

When using the slurry method, take soil from next to the plants, as well as some from further away. (Keep these two samples separate.) While this means a little extra work, you will get measurements that are more accurate since the amount of nutrients, types of soil, and moisture content can vary across a planted area.

All these things affect the pH of soil, so it's important to track your pH at many points.

How to Test Soil Using the Slurry Method

1. Gather some soil from the test area.
2. Take the homogeneous sample and add equal parts of soil and distilled or deionized (DI) water in a 1:1 ratio. So, for 25 grams of soil you would add 25 mL of water.
3. Stir the sample for 5 seconds.
4. Let it sit for 15 minutes.
5. Start stirring the sample again after 15 minutes, and take your measurement.

If you're feeding at 6.4, you're good.
I suspect TS will forgive me here.... You could follow TS's words above and get a feel for actual soil PH this way... but it's a distraction really. Just make sure the water going in is at 6.4.
Another thing to remember... changes take a good amount of time to take effect in a soil grow. A change to a feeding regime can take a couple of weeks to fully show up in the plant.

Heh. First, you'd have to do something that required forgiveness.

It's a bit more complicated than that, since the OP isn't growing in an inert medium. Your suggestion generally works, well enough. It's not the ideal way. In the interests of full disclosure, I'll admit I've done exactly that from time to time.

The real way to deal with a pH issue in soil is to amend that soil, for example, adding lime to raise the pH. It seems to me that if your soil pH is off and you are watering(/feeding) with something that is adjusted to a pH of 6.5, it'll not still be at 6.5 soon after you do it. The change measured in the runoff might not be significant (although it might be - remember that a 1.0 drop in pH means that a thing is ten times more acidic than it was), I'm thinking more of what stays behind in the container for actual use by the plant.

Cannabis is pretty adaptable. I think that can blind us to things sometimes. Make it easier for us to be lazy. If we harvest a crop and are satisfied with the quality and quantity of the harvest, we end up thinking that our methods must have been good ones. But, occasionally, we get that harvest in spite of our efforts, lol, not because of them. I'm a lazy gardener too (most of the time), but I am aware of the fact that this hurts my production because I didn't start out being a lazy gardener.

I try to recommend best practices (when I feel that I have a pretty good idea as to what those are). I have no problem with others offering easier suggestions; as I've noted, I follow the lazy road, myself, often enough. It's like... IDK... Like recommending that people change the solution in their DWC reservoirs on a regular basis even if the person giving the recommendation rarely bothers. We tend to arrive at our own methods/practices which are... often somewhat less than the official recommendations, so to speak.

Thank u all for the continuous support Here’s the update
Both are thriving
Lights is raised to 600w MH at 30”
Temps are 21-23.5 Celsius during day and 18-24 at night

Big baby is 54 days old little baby is 37 days old, big baby has been topped before, littlebaby is still a virgin
Shall I do something to make them catch up to each other or shall I just let them grow As they are ,?

I need another favor/ debate , shall I perform further surgeries or just let them grow into each other ?

An update
They are getting their feed tonight, and I’m difinitely messing with them one last time before scrog and flowering , maybe topping both of them , or topping big one 2nd time and fim the young virgin one , what do u think ?

 

[Tead]

I think they look awesome! Great job.
I'm not a plant sculpting kinda guy, so I'll leave those words for others.
