after some years of using "chemical" nutrients (advance nutrients, green planet, humbolt countys' own, ect) have finaly switched to "organic" nutrients (tea's, ect ) have found a few that are easy to use and very good results Elemental Nutrtients (myco based - 2 part) and Neptune's Harvest --(all have sample packs) anyway trying to make it simple , instead of mixing and mixing like a Mad scientist. but I still make tea's -- now I make Tariontional (alfala meal, enzymes, humic acid and kelp) which is a natrual organic plant stimulator which is simmular to Mammont P Have found one called "soil Balance" which if one is gong to enter a strain for a "cup" is one to use, really brinigs out terps and increased plant growth = bud size. (expensive) The only chemical I use is Massive Bloom (Green Planet) Guess nutrients are like seeds so, so many out their ; to choose from ---- when it comes down to it Water (water the spice of life) works the best all other stuff can enhance results but the base is your Genetics !!!!!!!!!!!
