I use the whole FF line up (Grow Big, Tiger Bloom @ 2 tsp per gallon & Big Bloom @ 1tbsp per gallon) and the Trio of Solubles (Open Sesame, Beastie Bloomz, & Cha Ching @ 1/2 tsp per gallon) never had a problem, at the most i needed to add cal-mag due to them getting deficient.
Also i grow clones so the seedling part i cant vouch for thought id mention that.
