white widow in need

what is wrong i never use over recomended nuts and at the hottest part of the day it gets to about 94-95 degrees but averages around 85. This is my first time using a drip system.

and how close are you to them ???? those 2 fans look terrible but the rest not too bad. try going with straight ph'ed water in your system for a couple days. on 2nd look its not the lights. whats your ppm ???? changing your water regularly

lower the ppm's a bit it looks like slight nute burn.

yeah totally agree

my "nuts "come highly recommended ah never mind............... its your "ph"
or too much nutrients( not nuts) maybe "nutes" but thats ph or nute burn .......! not a nut burn and go get some cal-mag they need more magnesium

Should i flush my system or can i just start adding water with less nuts. There is a little salt build up on the drippers but no deposits on the rockwool.

Yes, Flush

I think this is salt build up?
my friends widows's leaves look the exact same in my opinion, started like a brown wave moving inward leaving a yellow trail or just browning the entire leaf.
heres acouple of his widows

Isn't high 70's ideal? Temp I mean. If it is then up to 95 seems excessive.
