Need help. Leaves yellowing/curling. dying?[pics]

After the new 400HPS came in the temps in the room have been rising. Usually it has been around 85 but for some reason it has rised to 95 since a new fan was added. The plants arent looking too good...

Someone told me it might be ph lockout, but a few second opinions might not hurt.

The last pic is from a little while ago.

THanks!!

Well first off 95 is bad!! cooking your poor girls

I would say MAX 90F and even then that will slow down your growth.. if you can try and aim for max of 85F they will be much much happier. Any way to ghetto rig some venting right from the light? outbound of course.. that would help alot.

Need some more info to diagnose your leaves.. soil? nutrients? have you checked your ph?

First look i would say your fan leaves could definitely use some nitrogen..

Hey Man, I've taken a look at your pics! I used tin foil on my first grow and have not gone back since. It forms 'heat spots' on the foil and add's unwanted heat! You should try some 'Black And White' you can get a roll to cover a closet for about £15!
It looks like you have a decent soil but you could be feeding them too much, One Feed will do it for about 4-6 weeks. When watering put the pots in a bathtub/sink and put a jug of room temp water in, wait for it to sink through the soil, add as many untill you see trickling through the drainage holes then STOP watering. do not water again untill the soil is just about dry. these few tips have helped me over time.
Happy to Share

Well the soil is pretty much crap, couldnt find anything good around here. Using 20-14-13 every watering...which is appearently the wrong thing to be doing lol

The stuff on the walls is mylar, couldnt find any black and white around here either...

So what would you reccomend with fan placement? There are 2 exhaust fans in the top of the closet, so move one of them down to the light?

thanks again

edit: ph was 7 last time i checked
