Whats up ppl

I have 4 super lemon haze cuts in 20 litre buckets (DWC)

Room temp 26c-29c (somtimes reaches 30-31c I KNOW, NOT GOOD!!).

Humiditys up and down 37% up to 49%, when lights off 60/70%.

My tapwater EC is 0.4, i have 0.2 EC of nutes in my res's so thats a EC of 0.6 in all.

These girls have just put their roots out long enough to sit in the res now so should really get going but very slow new growth on plants

Also have this problem of the leaf tips are curling upwards, am i right in guessing it's heat stress? I noticed the change when i lowered my light, I've now put it higher to see how it goes.

Any help is appreciated.20180801_132454.jpg

It is not stressing the plant as much at those temps. 31C is what we call a nice sunny day where I live.... far from hot.
The problem in hydro is, if your water reaches those temps, it is useless for cooling the plant, and prone to growing bacteria and fungi that will kill your roots.
Root rot is an internal disease of the plant... i.e. once it had root rot, it never goes away, even if you took a cutting and start anew.

Roots look fine, nice and white mate, im using silver bullet which kills off pythium so i should be ok with root rot
