AM i doing something wrong? Plants looking sad..

I was wondering how my plants are looking. They seem to get a bit curly meaning the edges are rolling downwards.
Is this a heat issue or underwatering?
I went with 1/4 strength nutes and went full strength after a week the plant got a bit nute burn on tips so i used straight water since. Does the plant need more nutes? More water? Or is it heat issue?

Im using 16 cfls 26 watts. They turned looking sad ever since i changed the lights to 12/12. They are 3 weeks old and almost a week old in flowering 12/12. Started it early due to space issue.
Some plants are looking healthy but some parts of the leafs towards the bottom are curling up.. Maybe the sides are lacking light?

Any help would be appriciated.

Thank you.

plant could be curling down trying to avoid heat

Oh that makes sense since my temps are 90f+ when lights are on and 75 ish when they are off. They are about 1~3 inches away from plant i think im gonna be raising the lights a bit and trying to get it cooler in there.

Thanks!

Any other input?

I also noticed some browning on some tips of the plants very slightly i felt one of the leaves but it didn feel dry at all. Maybe im underwatering or not enough Nitrogen.
So i just gave them another water feeding with full dosage. Hope they respond from it.

HOLY CRUD 90F when the lights on? That is the problem, for sure! Just get those guys cooled off with some nice moving air and you should be set ... once they cool off you should be gold! Browning of the tips could be from nutrient burn. Careful with it...they seem to be past the germinating stage so they are a little heartier. If they start going south, stick with just regular water for a while.

better get some air moving and lower those temps

Well the temps are around 78~80 ish F lights off and 85~92F with lights on..The box it self is a small amount of space under my basement. The space itself is closed shut with a door and inside that room i made a sqaure space where i have another door which is where i have the plants.
I have small desk fan and 3 pc fans blowing at the plant. I dont have anywhere to exhaust the air but i think im gonna get a 6inch inline fan and make a exhaust to the other room even tho it doesnt have any air coming in or out maybe it will help the closed space.


Does flowering make the plant a bit droopier/sad looking than vegging days? These started happened ever since i changed the bulbs to 2700k which is hotter or the light cycle 12/12
