kinda glad there not.....just realized I have no idea how much nutes I should be giving them at what stage anyway....... The nutrients I have are general hydroponics micro, grow, and bloom along with hygrozyme......... Should I just follow the suggested ml that came with the waterfarm? Is it safe to use full strength hygrozme (8-10ml / gal ) during entire grow? any other comments good/bad about my grow and setup? .......still new and want to learn EVERYTHING.
