its funny cause im using dry fert and chem fert. 10-30-20 mix with kushie kush,hydroboost,diamondnectar,koolbloom,karbo boost,koool bloom, rhinoskin. I use the kool bloom and karbo boost and mixed with the 10-30-20 and diamond nectar and half strenght rhinoskin(after week 4). in the start (week 1-4)i use kushie kush and hydroboost mixed with diamond nectar and 10-30-20 and rhinoskin.. im going to add a few table spoons of GH micro in the mix to balance out everything. But i think the 10-30-20 contains all the nutes but since im adding bloom boost and more P and K from differnt sources with only mg as secondary. I think it would be better if the extra micro was there
