its about half the mature leaves, so maybe 25%. I don't use nutes . it's water only soil and I use my own w.c. for a compost tea about once a week. i dont think its calcium deficiency because my well water is high calcium.
so you leaning towards calcium deficiency? should I worry about it being so close to harvest?
great lakes water only soil, worms are fed with a lot of different food scraps and coffee from home and a freinds restaurant (kind of a high end organic breakfast and lunch place, sweet hook up for worm farm and hot compost), hardwood saw dust from my shop and paper bags.
it's all the bigger mature leaves I'd say 20% of the fans. I was looking at pics from last years runtz and they had way more fan leaves. I usually let them get rained on or use water from the rain barrel but when it's dry I bypass the softener and use the hard water. it sucks for home use to so r/o is coming soon. check out the pics I've posted and tell me if you see anything else. I've been going for a few years and still pretty new.
Calcium or manganese issue my eyes are not the best
Slight calcium or manganese def like others said. But you're far enough along I don't think it's a huge concern at this point. Give em some Calmag from now on when you water. 1/2 strength every time will be enough, and won't hurt anything. (2-4ml per gallon of water)
