well... I dunno what youre feeding them, but 30-10-10 is pretty potent compared to what I use.
I usually go with 16-5-4 for veg (a combo of bat guano and fox farm grow big) , For the transition, I usually go with bloom guano and fox farm grow big so I guess 6-15-5,
and when in full bloom, I use fox farm big bloom(#'s are too low to mention, I use it more for the mico's) fox farm tiger bloom, and bloom guano, so I think the #'s would be something like 3-18-8
ETA: Basic rule of thumb when growing just about anything is.... ya cant go wrong with 10-10-10. Just about anything will grow with those n-p-k values. Everyone has their "special sauce" to make the girls do what they want tho....
