I use ffof and technaflora nutes myself.for 4+yrs. LOVE it.
Couple tips for ya
Add 1 cup powdered dolomite lime to 1 bag of ffof soil and 30% perlite. Helps buffer ph, and the perlite cuts the soil a tad more.
Sugardaddy- ditch it immediately
Grab a bottle of botinicare sweet raw. Same thing as SD, BUT it's a lot cheaper, only need 10ml/gal of sweet vs 15ml of SD to get the same potency. So saving two-fold.
Depending on how much nutes tou use, buy bloom, boost, and sweet in 1gal jugs. Thrive alive red, awesome, and magical in the medium sized bottles.
I always use full strength, 100% feedings. Never any issues even when I run 10 different strains. ALL my girls love it.
