Hey whats up ?? I'm new to this site,and this is my first grow in a while. I'm growing 2 plants from bag seeds. They are in like the 3rd or 4th week of flowering. My question is that I'm growing in merical gro moisture control soil. And it looks like my girls need some extra P & K. I can't find any nutes that just have p and k without the n. So I came across some stuff called Espoma triple phosphate. So should I use that and if so how and how much ?? And could I add molases and some banana peels for extra k ?? I just don't want to add any n or to much p and k because of the time released nutes in the soil. Any help I can get would be appreciated.
