Heat stress?

Hi guys thanks for taking a look at my thread, i have a plant that is having some problems that i believe to be heat stress im just looking for confirmation, i figured they would be fine because it was just 6 cfls in a closet, but i had not set up my ventilation or thermometers yet, anyways i just put a thermometer in at canopy level near the plants and found that the temps were ranging from 90-100f so i set up my ventilation and the plants are now sitting at a stable 86f more less.

What type of medium; soil or hydro?
soiless

What brand and type of soil?
slightly augmented vic's super soil

Indoors or outdoors?
indoors

What strain?
white Russian doing fine and blue cheese not doing so well

How old are the plants?
1 month

What type of lights and how many watts?
6 27 actual watt 65k cfls

How far from the lights?
a few inches

What is your watering frequency and source of water?
every 3-4 days Reverse osmosis water PH adjusted 7.0

What, how much and when was it fed? NPK?
The soil is premixed

What is the medium/runoff pH and PPM if in hydro?
The run off was always 6.5 but i have stopped checking since transplant


What are the temps and humidity in the room?
The temps had been quite high recently as my ventilation was not ready to go and i figured i would be alright since it was only 6 cfls, but i recently put a thermometer at canopy level with the plants and the readings were from 90-95f i have since gotten the ventilation taken care of and the plants are pretty stable at 86f.

What size pots?
1.5 gal air pots

Any bugs? Look real close.
I don't believe so

The first 3 pics are the blue cheese that is having the problems the last 2 are my white Russian that is doing just fine.

looks like to much N

Really you guys think its nutrient burn? Ive had nutrient burn before and this doesn't seem like it, it took a long time to start looking this bad and growth hasn't been stunted at all its actually been quite vigorous i topped 3 days ago and it already seems like it has recovered , when i got nutrient burn last time it happened fast and growth stopped all together for a bit, i transplanted the plants into the new soil 11 days ago and noticed no signs of nutrient burn. Also i started the seeds in jiffy seed starter mix and waited until the plant was on its 5th node and the bottom leaves started to yellow and die to transplant into the new soil.

here is the list of ingredients i used for my soil.

2.8 cu ft promix
1.0 cu ft ffof
8 cups Bone Meal 0 10 0
4 cups Blood Meal 12 0 0
25 lb pure worm castings 1 0 0
7.3 cups green sand 2 tbsp per gal
4 cups powdered dolomite lime
4 cups kelp meal 0.6 0 1.5
Epsom salts
25% perlite

hot soil..........ride it out.

Well that's a relief i was starting to think it had a disease or something cause this plant has been pretty finicky from the start, its just surprising i guess cause like i said the growth hasn't been stunted at all and it took 11 days to get this bad, last time i burned my plants i noticed it like the next day.

those temps will eventually cause stunting and other trouble, imo. cool things down

I just got my ventilation finished yesterday its on and maintaining a temperature of 86f it would be cooler but our ac broke last week and i haven't gotten it fixed yet

Regardless of temps go buy a power ade and a bottle of yeast. Slam the aid mix some sugar yeast water and replace the cap. Pressure builds over time and releases in bursts so it's more even doses, place infront of fans aimed at plants. Like +20 to fire resist you dig?

Get the temps below 80 or your final weight will be reduced.
