What is wrong with my plant?

[chewmills]

I have done a couple of grows but was fortunate enough not to have any real problems, so identifying issues isn't exactly my strong point. Could anyone tell me what is wrong with my plant, please?

I am using an LED light and it is growing in a hydro system. I am struggling to control the temperature in the tent and, although today is by far the hottest it's been, it normally ranges from 30 - 35 degrees.

Cheers!

Advanced nute burn, trash the rez clean well
then circulate or just feed water for 36 hours,
then feed at 50% less or until you see some uptake

tho you may well be following the label on feed time
you gotta allow for evaporation in a hot climate

a small fan and temp gauge close will help

good luck

Ah, that makes sense. Thank you very much!
