Is 1.9EC / 990PPM too much nutrients for autoflowers at any stage?
I am currently at 1.0EC / 550PPM with Jacks 3 2 1 at 50% and wondering if autoflowers can generally handle Jacks 3 2 1 at 100% which is around 1.9EC/990PPM?
I am currently running an autopot (bottom feed) with 50/50 Coco/Perlite.
When I did full strength, I saw some major nitrogen toxicity but I am not sure if that was because I was beginning flowering.
