Bro you got way to much nitrogen you are going to foxtail and those pants are stretched way out and that's cause you don't use a HPS LIGHT brotha I'm at week four is day 26 check me out I'm using hydro though I would use a three part with your basic additives Im not familiar with the fertilizers you mentioned

So plant as a whole looks well but what is this funky shit? All organic I added 2 table spoons of Gaia green power bloom a day ago so its not that. Any help? These stalks and this plant is a beast wouldn't want things going wrong. Front plant looks mint. This strain is Apple Punch. Demon sweat x Platinum mintz

Thanks!

Dude I had to create an account just to reply to this. It was going to give me an aneurysm if I didn't say something. With all due respect @Trash_2002. My personal experience has led me to a a different conclusion based on the little information we have to go on.

Disclaimer: This is ultimately my opinion, I do believe it's relatively educated based on my experience but there is a lack of information since I'm not there and I'm missing some important bits of information to have a fully formed diagnosis.

Trash_2002 was barking up the the correct tree. I experience this canoeing far more often than I care to admit. My operation is in Southern California and in the summertime the low outside humidity and high temperatures leads to me battling for environmental control. The score is measured in VPD. You can tell if I'm losing based on canoeing especially towards the top of the plant.

Yes too high of a temperature does technically lead to this but it's too high of a temperature with too low of a humidity. To an extent you could read too high of the temperature as also meaning the exact same thing as humidity being to low.

There are 2 questions I need to know the answer to to best help you. Assuming you don't track your VPD

1) What is your humidity typically like during the day and at night high/low/typical.

2) Same for temperature. Which you've already told us.

So just the humidity.

I'll take a stab right now and say its probably just at or more probably below 50% with lights on

If so, that's the problem with the leaves canoeing and you can fix by getting your Lights-on VPD under control. Which means lower temps and or higher RH. Your temps are fine.
I could give you 1000 words on VPD and why it's crucial to our endeavor. The quick version is "VPD can be thought of as the direct influencer of plant comfort. Is the environment trying to suck out moisture faster than the plant wants to give it up? If so one of the few things the plant can do to limit this moisture grab is to close it's stomata. Poof no more water can get sucked out but no more CO2 comes in and photosynthesis stops. Not good.

Which leads us to...
my rant about light poisoning or whatever people call it. Your lights are fine. Too much light is not a thing. The real problem is what ever your new limiting factor is once light no longer is. See light is what normally what limits the plants photosynthetic activity. This stops photosynthesis before the limits of CO2 or anything else are reached. Without light to stop it other deficiencies will show their head. The next one is CO2. If you're supplementing CO2 the next one is probably nutrients What ever it is though it means the plant is unable to supply the other ingredients needed for photosynthesis and the excess energy obtain from light has to be used up somehow which it does pretty much through converting it to heat. This can be evident when the upper leaves are canoeing and getting crispy. Yes the solution to this can be to turn the lights down/raise them but the root of the problem is lack of CO2 or nutrients which when supplied will fix the problem therefore lights aren't technically the problem.


Last thing... Pictures are not great for nutrient diagnosis and hopefully someone more experienced in and soil based growing can jump in but that shade of green is a little pale for me taste. I'm a hydro grower so my solutions for this probably are not applicable. Get it?

I meant to also @hokageC in the beginning when prefacing my post as only my opinion

Yo, Thanks for the help! Quite thorough with your information which is super appreciated. So here is the answer. My humidity has been around 50% to 60% this entire grow as my swamp cooler kicks up humidity. It may have been that I didn't water for like 5 days once. This happened a week and a half ago. New growth around pistils is nice and green. Also leaves are not crispy, yet anyways. I did add power bloom gaia green a few days ago hopefully this will add the nutes it needs! I will also be sending a video so you can see better! Thanks for creating an account just to help. GGs

Actually if you can check out my recent posts on IG they are videos. Me trying to upload a 45 second video is too big for the servers it says ....

 

[Trash_2002]

My tips were exactly for this reason, bringing down your VPD ;-) and lower leaf transpiration tho.
The up in nutrition could help alliviate the deficiency.

Cheers

Sometimes temperature raising will raise humidity too, more transpiration, hot air holds more water, to talk real VPD we need Leaf Surface Temperature with flir cam or a good IR gun thermometer.

Generally speaking:
Higher temperature will raise VPD - And raise stress levels
Lower RH will raise VPD - And raise stress levels
Lower temperature will lower VPD - And bring down stress levels
Higher RH will lower VPD - And bring down stress levels

now light levels, what's the point in blasting them with 1000ppfd if they are clearly not handling it well. So you have to lower the VPD and lower light intensity to get out of the high stress zone ASAP.

I water mine once every 7 to 10 days I don't think not watering for 5 Is an issue im week 4 of flower as well.

You guys are dope thanks for the help!
