I think it has to be hard wood like oak or mahogany but I don't know.but 5-1-1 aint gonna do it for flowering.also I think ash raises the ph of ur soil.u need to find a fert that is like 1-3-4 or something like that
Yea i agree im using The fish fert for The nitro i use 1/4 the normal dose my plants love it.
