It has no npk value.... it has a potassium-humic content of 4% which has an organic origin...and micro elements....
It has a overall K2O content of 2%....
Growers around here say that it is a good stuff... as i said, it should be used foliar, but i only water the plants whit it...they seem to like it, but i'm a little worried that it could cause overdose symptoms later during bloom....
