Which ppm scale are you using?

 

I would be wary of upping the ppm when a plant is stressed.

 

From the info you have given I'd lean towards the environment being the issue. Until you take care of the excessive temperatures you won't know anyway. Eliminate this as  possibility first and work from there.

your ppm is low... should be around 1000ppm.

you could drop your ph to 5.8 that should reduce N intake a little and bring Mag intake up to help with leaf stress.

running silica will make your plant more resistant to all things. Hot, cold, over water, under water, nutrient problems, pests.

running distilled water would usually require using some cal-mag

dont think its the problem atm for future reference. running nutrients through chiller has created nutrient lock out issues. depending on nutrient brand solids can settle in the heat exchanger of the chiller and build up over time.

 

what do your roots look like?

Roots are exploding with new growth daily since adding chiller , have been nice n white until I put the calmag in now kinda brown but clearing up

I notice you have your airpump in the grow area. If it's 35 degrees in there you are pumping 35 degree air directly into the rootzone. You should move it outside the area hopefully to a spot where you can pump cool air into the rootzone. Even if you have the water chilled the hot air will cause problems.

Yep I'll do that , it can move next door with the chiller , I do have a tube connected to inlet on air pump sucking air from under neath where my inlet vents are , it's quite breezey because of air being sucked it in but the pump itself does get quite hot , probably overheating from sucking air thru tube ay ?

definitely looks like an over watered plant ie: drowning, lack of oxygen

Is the air pump your only source of air to soup or are you also running a waterfall?

My air pump is 38 liters a min and res is cool, I have ordered a new air stone tho Edited January 21, 2016 by c0bblep0t

I have 13mm elbow just inside so water drops about 3"
