i use the stuff bro:thumbsup:

the folks at my shop sell it to peeps for hydro...it has a higher npk than the hydro version :thumbsup:

not sure why they have 2 types when they are both very similar with the only difference being in the npk from what i could find comparing the 2 bottles side by side!:wtf:

under HPS i was using at 40ml/gallon at the end of flower! ihave had to change my feeding schedules since switching to LED because my last harvest my plants were so green at the end and i flushed the crap out of em' and only had one leaf discolored out of 16 plants!
