phosphorus supplement
I have used 15-15-15 fertlizer for my hydroponic tomatoes. The plants
rooted very well and also the foliage is very strong green. But it
does not seems like there a lot of flowers coming up. I beleive I
should put something that contains more Phosporous. (second ingredient
in fertilizer ).
Does anybody knows what is a good supplement of just the phosporus?
