Hello ! Yes you are right, yellowing between veins and purple stems are the main signs of Magnesium def and they can be seen on your plant. Increase your cal mag amount and it will be ok ✌️🏼

Yes, textbook mg deficiency. You know, once the flowers have formed (3d or 4th week or flower) switch from cal mag to a magnesium / sulfur additive, like epsom salts.

hey @indekast , yeah you absolutely got the start of a magnesium deficiency you can tell from the yellowing in between the veins eventually spreading to the rest of the leaf. you know what to do but : up the cal mag, lower the PH to 5.9, and they will recover in a week or less, hope this helps bro ! 🚀

Can anyone tell me what the issue is looking at the pic of the affected leaves? I don’t think it’s nutrient burn since I’m growing in coco and using organic nutes at half the recommended strength. The overall health of the plant looks pretty good but I can’t help but notice this.

Intervenial chlorosis, thick wrinkled leaves. Ph imbalance or quantity of nutes? Will adding CaliMag back in help? Trying to avoid burnt tips issue Hard water (7) lowered to 5.8. Last week: 1 gal 3 waterings, w FloraGro (2.5 ml), Micro (2 ml), Bloom (2.5 ml/), Hydroguard (2 ml). Last grow had burnt tips and possible N deficiency, so I was trying to avoid that. This week I've switched to GHE's schedule and added CaliMag.

Leaf diagnosis: nutrient burn or deficiency (or both)?he leaves with the burnt tips appear to be more prominent at the top of the canopy, only affecting new leaves. A handful of these leaves look a little twisted. Meanwhile, the yellowing leaves are more prominent in the middle of the plant, just below the canopy
