Diagnosis:

First...your soil is wrong.

Second...your PH is all screwed up

Third...Heat stressed plant

Fourth...Lack of Cal Mag in feeding

This all adds up to a perfect storm of FUCKED UP. :jointsmile:

Solution:

Flush your shit. Get real nutes. Read these forums before you rush into your next grow. You might want to consider transferring into a large pot with FOX FARMS MIX...and go from there.
