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 ✌️🏼
Athosanswered grow question 5 years ago
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 ! 🚀

Spotted Leaves – somethings wrong! HELP!(See previous question as well)
The girls are getting worse 😬 Only the bottom leaves seem to be impacted though.
Only thing I've done today is water them (three day since last and they were dry).
Any suggestion to what might be wrong with them?

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

Intervenial chlorosis, thick wrinkled leaves. Ph imbalance or quantity of nutes? Will adding CaliMag back in help? Trying to avoid burnt tips issueHard 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.

Does the discolouring I'm seeing (looks dark purple) look like a deficiency or is the plant just using up nutes stored in the leaves? Please see W14 photos.Week 14
