Beginning of the week there was a calcium deficiency ( diagnosis looked at similar grow questions) so I got a more reliable Ph meter, and at the end of the week there was a new problem, it's time to ask for advice
Also remove 2 large bottom leaves and 2 inside for better air circulation
First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared.
Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.
I think your original idea of Calcium was accurate. The damage will not heal it will just stop progressing on new leaves. The old leaves where it already showed damage is likely just necrotising a bit and I think this is normal for that leaf. It should not be appearing on any other new leaves though. If it is, this might be a build up issue.
I do think the feed of 1.5EC is a bit high for the plants size, and I hope you are getting some runoff in the feeding/watering process. Double check their suggested rates of what bottle and the amounts then dilute down to a ratio you think is best. I feel 1.2 is ok for the size of this plant. if you can check the runoff EC and PH that may help show whats up, not the first bit that comes out but the mid/end stream.
Good Luck!
I watered it last night. in the morning everything was fine, after 8 hours of day I saw a problem, on near Lemon AK something similar but smaller (the last 3 photos). Water them with one solution. I also did the spraying, but almost 24 hours passed. Light fibers are poplar fluff.
what do you mean when you said you "did the spraying" ?
Don't sprays plants in bloom with anything, feed via the roots. Pistils will get damaged and die back, I'm guessing that is whats happening here your foliar fed them?
