I hear cigerette ash is high in phosphorous and potassium though i think it may be more potassium than phosphorous. Will this help plants during flowering like bat guano etc. AND ULTIMATELY SHOULD I TRY USING SOME?
It's doing a few of things. It's providing carbon in small amounts and some K. It's also jack your PH up which will eventually lock up the nutrients unless you correct it with some low ph water.
I wouldn't do it. There are a lot of better ways to feed your plants.
