It is a magnesium deficiency. So cal mag would be the answer. Unless your ph is off. I see on your diary your ph is not listed. I would start with what is your run off ph. If it's out of range plants can't absorb the nutrients. Causing deficiencies that you might not really have. Around a 6.2 6.3 is ideal. Also if you are using coco coir you will need calmag . Good luck and that should help a lot. Happy growing 🌲🌲🌲👊

I believe It's a slight Potassium (K) deficiency - Yellowing tips and margins with slight chlorosis and mottling/blotching.
Increase your Potassium output (usually in high concentrations in "bloom" fertilizers) and lower your Cal-Mag usage to 0.5ml/l max, those are micro-nutrients needed in small amounts and constant feeding of it will cause a toxicity! (Calcium toxicity inhibits Potassium uptake so it might be an option as well).
Hope this helps! Good luck and happy growing :)

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.

Pineapple auto in soil tiny brown spotMy pineapple express auto is well into flower but the leaves look sick with light green patches and tiny brown spots appearing on some of the top leaves. The brown spots dont rub off on finger so don't think it's fungus. Not sure what I should do, it's getting flower nutes.

Why the twisting/wrinkled leaves?Why are the leaves curling/wrinkling/twisting?
The plant seems healthy over all, about 9 inches tall/4 weeks old. It looks as if the leaves are too close together causing it to wrinkle, but that also doesn't seem like a correct guess.
