Hello, i've got some og's and a dj shorts blueberry outside flowering, doing ok but i'd like to find a nutrient solution that is ph neutral itself, and also good quality. I don't like adding ph-adjusting solutions to my mixed water as i'm concerned they are just more junk for the plant to uptake instead of nutrients and could build-up or who knows what over time. So, has anyone used/been using any ph-neutral bloom nutrients for soil they liked? Thanks.
ph neutral bloom fertilizer?

monopotassium phospahte. Barring that, GH Flora Bloom. cn
Interesting. I'm doing some reading on mono potassium phosphate and it sounds like it works well as a buffering agent, but can be slightly on the acidic side itself? Thanks for the advice on the flora bloom. also for reference i'm using r/o water that comes out at about a perfect 7.

By itself, it is slightly acidic. My mixes come out in the high 5s, ideal for hydro and fine for soil. Most soil contains lime and other proton sponges, so I think we can get away with calling it pH-neutral. In unbuffered soilless/hydro, I'd say active pH control is necessary, but soil is a buffer. Especially if you admixed dolomite lime ... the magical pH leveler. cn
