Whats your temp in the room?
The canoeing points towards heat...
but the crisp discoloring and crazy wilting...I've experienced from burn...
do you check you Ph before feeding?
When you say "whole line' ...please list... both companies make a LOT of products... I doubt you were using all of them...you'd be jumping ship on like $200 worth of nutes...
(ie...Grow Big, Tiger Bloom, Big Bloom ,Open Sesame, ChaChing, Beastie Blooms, Sledgehammer, Microbrew, and Kangaroots... would be "the whole line" of Fox Farm nutrients...
