My plants are in their 3rd week of veg, and I am going to start lightly feeding them some organic ferts.
I have some blood meal that is 12-0-0 and some garden manure (dehydrated poultry manure) that is 4-2-2. The brand is "Espoma Organic Ferts".
I am worried that if I add these ferts, they will screw with my pH. I am under the impression that blood meal is acidic, so I have some pH Down to counteract that. On the other hand, Im also not sure how, or even if poultry manure could "burn" my plants.
Any information or experiences would help me out alot guys, thanks in advance.
