It is calcium deficiency. And if ph is not stable then the feed amount is not right. If ph goes down feed is too strong, if it goes up then feed is not enough. From my experience I am betting it is going down. 2 of mine both did this, and got a strong dose of nitrogen just like yours. .1 ph in Hydro is a big change in what nutrients the roots can absorb easiest.

Each plant seems to be suffering from some sort of deficiency/lockout. I thought the 4AM & 3BOG looked hungry but no improvement after 2 days. Sour Stompers still losing leaves but their buds are MUCH fatter and frosty than the other 2. Maybe just different flowering times.Week 7

She looks healthy yet this leaf.....Does any see this before?
I have 3 more plants that use the same setup and all others are looking good. So I don't think this is caused by bug/nutrient/light/PH

Brown patches in leaves late into floweringI noticed some brown patches on
my leaves late into flowering, almost as if they were dirty. I started flushing a week ago. Is this normal or should I do something? The plant is almost ready to be harvested, maybe one week more.

Almost two weeks old, got her first spot on a leafWhat do you guys think is the cause of this? She is only 13 days old. Is it a light burn? She's getting 16-20 DLI until she develops more leaves. Wind? I'm not giving any nuts yet. Even her last water was like a week ago because her soil still feels a bit moist. VPD Early Veg.😽
