phosphorus problem

got any answers?

during flowering you want mostly phosphorus then potasium then nitrogen. as the flowering period moves along i lower my nitrogen levels

so my bat guano should be good to start the flowering then maybe in a few weeks put ashes in there while lowering the nitrogen? does that sound right. also ca it be from any kind of wood like cedar or redwood?

that sounds fine, if your nitrogen source is from the bottle of nutes then just dilute the mix more and that will lower it. if to much nitrogen is left in the soil it will lock out other nutes.
as far as i would GEUSSE there is probably different nute levels in diff wood. never looked into it. i dont use that method
