hi, ive been looking whats inside , its 7 percentP and around 6 percent K. Not to heavy for a booster....youve been doing great with your fertilisers ..... but its your decision... i would do it.. because no N inside that could harm her/ them
..... regular boosters got 12 and 13 percent or more inside.......i see no big prob to use it.. maybe look at tazard grows he used the same products
