i would use big bloom everytime you water at 4 tablespoons per gallon.
If it IS Big Bloom, that is. Fox Farms Tiger Bloom would kill your plants in one day if you watered them with it at that concentration. I'm just making sure, because you said Bloom formula and they have two products, vastly different from each other. So which is it, Yellerz? Trying to avert tragedy!
My BAD! It is TIGER BLOOM!!! I just gave them slightly less than directed. I don't think I over did it cuz they were some happy, perky, stinky bitches this morning...lol
OK, now how often am I suppose to water??
