    Use both, the acid to recover the PH, and the buffer to keep it there.

        Pelleted sulfur is a PH down buffer, pelleted dolomite lime is a PH up buffer, they work together to keep the soil balanced.
        Sulfur with air and water make sulfuric acid in the soil.

          Hello here again. Same problem - in this phase, flowers going to this phase - upper leafs going brown from sides, idk why. Ec is ok, ph on watering 6,5 decreased by h2so4. Is there something missing or heat stresss or what is that? Until now it was after ph correcture ok. Now, as last round, in this phase flowers going brown and startto dry (these leafs). Why? Thanks

            might be a bit of light burn? what type of light are you using and how close is it to the top of the plant?

                But it would start earlier than in this phase, or no? They are not growing up like 2 weeks

                  20-30 cm ...which one is it? 20 or 30? either way that seems far too close...remember light burn is based on intensity not heat so a light that's 150W at a distance of 8-12 inches is way too close IMHO
                  I hope there is an afterlife...there are a lot of friends and family I'd like to see again, one day.
