Quite literally have never seen this on my plants before, any ideas? I’m in promix, using black swallow all purpose and bokashi emended into the growing medium I have not started any other form of calmag or bloom mites yet as she is literally only in week 1 of flower, her next watering I’m going to start her bloom nutes and calmag. But any insight would be greatly appreciated
