I have high P guano for phosphorus, but need something for K, I have kelp meal mixed into the soil, but I want something else for more K in flowering.
Should I get another guano that is high in K, or a soluble kelp, I found a mixture of soluble kelp and soluble humic acid, would that be good? Better than just soluble kelp?
