Bingo, those are mite bites. As long as the plant and new growth are happy dont get caught chasing ph. Get the mites and gnats under control. That is NOT a calcium deficiency. Or any that i can see...i do have fungos gnats and spider mites, but its my high runoff im worried about. my guess is the high soil ph is locking out my plant. how do i lower my soil ph? should i just use lower ph water next feeding?
