i dont have an ozone generator and the nutes i use; advanced nutrient micro and grow both contain Mg, so im kinda confused??

Ph spotting can look like that and typically its Calcium def. not MG that does that(I was told MG too but it turned out not to be). Mine looked the same and ph run off was 5.8 (soil) I flushed and brought the ph back up but it never fully recovered. I am a week from harvesting and my plant looks like shit But the buds look great.

Check out my thread a few down from yours
