1ml/gallon max for week 2 and potentially week 3 as well. i used 2ml/gal and all my leaves acquired a curled look that basically didn't go away (on my current grow, first time i've used it). that said, it does increase yield and helps stop stretch, and the buds don't look weird like BM. I might even try the half a ml/gal, you really don't need much. all this talk about cancer from phosphoload sounds like hearsay, i would love some links to studies or anything that can show that this or superbud "causes cancer". Does it make my smoke worse than the air in LA? Probably not! But if it really is toxic, i'll stop it, just want some evidence.
Never use what the bottle suggests, you will kill your crop. God only knows why they left those directions on the bottle--they would never get repeat customers if people followed the label.
I can't comment on taste as i havent cut yet, but it does look like it works for yield, and the plants are robust.
