you would like to be bellow 95 if you can, you just need more ventilation to your room and a fan removing heat from the area connected to your cooltube to accomplish this.

I totally agree I'm planning on getting some ducting here soon.

Update week 3 sense sprouted leaves are starting to yellow

Anybody know what this could be

 

[KingJohnC]

it would help if you posted in your journal how many days of vegetative growth you are at, the pH, the ppm you are feeding and how many millilitres you are feeding per gallon of nutrients. you may want to increase your nitrogen a bit but it is hard to say without knowing how much of what you are feeding. the leaf damage may be from the pH swing , i saw you had your reservoir as high as pH 6.5.

here is a nutrient availability chart that may help you understand which nutrient may be locked out and create a deficiency.

here is a cannabis leaf deficiency chart i hope it helps you.

Hello OP420

KingJohnC has posted some excellent information.

From the pictures, I concur that you are having issues with heat. This can cause many different symptoms - including apparent nutrient deficiencies. It almost looks like you are having a sulfur deficiency with the light yellow colored leaves on top of the plant.

Also, with the pH problems, you could have plenty of sulfur and yet have it locked out.

For success, you really need to get your temps down and to get the pH between 5 and 6 - and then keep it in that range. I try and keep all my systems between 5.4 and 5.8 - and it seems to work very well. I try and NEVER let the temps go above 78 - and I really prefer 74... which is hard for me to achieve.

Appreciate the info. Here is where we are at far as info.

I got the room at 85 and holding steady for 4 days now with it being around the max temp outside for this time of season. I am feeding 10ml of flora grow per gallon and 10ml of flora micro per gallon, and 2ml per 5 gal of rapid root. i am using 7 gal of water for this dwc.
My water before nutes.
Ph-6.5
Ppm- 55
And my water after.
Ph-5.4
ppm-660

My light is 400w MH running on 50% percent power it's about 3ft above the plant. All this info besides the temp has been from the past 2 weeks of res changes.

Still a little high - but much better.

I am feeding 10ml of flora grow per gallon and 10ml of flora micro per gallon, and 2ml per 5 gal of rapid root. i am using 7 gal of water for this dwc.

I have a spreadsheet that I use to do an elemental analysis of the nutrients that I use (you can see an example of this in my grow journal). I took the liberty of putting your nutrients in and running the analysis.

In short, it shows that you have ZERO sulfur - which is not good. You are also running WAY low on phosphorus. And your ratio of P to K is way off as well. You are not using a balanced nutrient solution that the plants want right now.

I would do away with the rapid root - it is not adding much at this point, IMO.

You are only using two parts of a three part mixture - and thus your ratio of nutrients is off. The part of the mix (for the flora series) that you have not included (the Bloom) is actually fairly important - even when you are in veg as it provides lots of things required during both veg and flower. It is the only one of the three parts that includes ANY sulfur. It also contains a good ratio of P to K - which will be a major benefit to you right now.

If I remember correctly, the Flora series suggests an equal ratio of Grow, Micro, and Bloom. To get you started, and to give you approximately the same PPMs as you are using now - I would suggest that you start using a balanced mixture of 6ml/Gal Grow, 6ml/Gal Micro, and 6ml/Gal Bloom. With your water - this should give you a PPM somewhere right around 600 - A good starting point on the road to recovery.

Once they recover, work them back up to 10G/10M/10B. Once you reach this level, you will be just short of 900PPM. You can do this by starting at 6, then at the next nute change move to 8, and then finally move to 10.

I would prefer the pH to be around 5.8. You should try and keep it in a range from 5.6 (min) to no more than 6.0 (max). Everything else looks good.

My light is 400w MH running on 50% percent power it's about 3ft above the plant. All this info besides the temp has been from the past 2 weeks of res changes.

Effectively, you are only providing about 200W of power. At 3 ft away - this is not enough light, IMO, to foster good growth. I would put the light about a foot to eighteen inches at most from the plants. So place the light at 18" - when the plants are 12" away - move the light up another six inches. Repeat till harvest or you bump up the power.

Make these small changes - and everything will straighten around in no time.

my friend.

I would also suggest using silicon in your nutrient solution. Again, it is not provided by the base nutrients that you are using - even when you add the Bloom in.

Why would I suggest silicon? Because it helps a plant to handle stress (such as high temperature) much better. For soil grows, nearly 1/2 is silicon in one form or another (quartz present in sand), but hydro has zero silicon unless you add it explicitly. This has something to do with the fact that you can't get silicon to mix properly with the concentration of nutrients used.

I have switched recently to Dutch Master Gold Silica - again, there is a note posted in my latest grow journal explaining why I am using this now.

Any update on the plant?

Has it continued to suffer - or has it recovered yet?

Sorry been Mia rough on money and computer broke but yea the plant is well and established. This is week 7 of veg gonna flip the lights here soon

 

[TaylorMade420]

good stuff mate, looking forward to seeing some pics

 

[onlypotent420]

It's been a while sense some pics so here it is week 7 of veg. Been doing some lst'ing so let me know what y'all think

 

[GreatLife4All]

Looking very good

Sorry to hear about your troubles.

Thank you I got the pics uploaded take a look

So it's weak 2 of flowering we are in early bloom bud sites everywhere! I did a little defoliating today soo I have some before and after pics. The leaves at starting to get blue hues back which is escorted dooring flowering with Blue Mystic let me know what y'all think

And these are after defoliating didnt take to much just enough to get good air flow.

Can anyone tell me when should I lollipop? And do I do each shoot or the main stim I lst'd her don't have more than one main

 

[GreatLife4All]

I do lollipopping right before I put them into flowering.

I trim 1/3 off the bottom and leave the top 2/3s on. You can then trim again 21 days into flowering and get a great shape for budding.
