Over feeding, cut back on your feeding! Use more minerals! Kelp and magnesium sulphate!

Go to the General Hydroponics website and follow their directions. Your plants seem to be suffering a calcium and magnesium deficiency and look under watered too. Try and aim for a pH in the low to middle sixes range.

I’m just a beginner, so I’m going to leave the diagnose to someone with more experience. But I just want to add that it’s possible to grow start to finish 1:1:1 with the tripart. I use these nutrients too and had no problems since I did 1:1:1 (first grow, 11days in flower atm. I just wanted to add the fact)
