Depends If coco is present in your substrate. If so then I would use it more often then not coco absorbs cal mag.

Hi Legend, Not sure about it. Magnesium, Calcium, Ph. Maybe uptake or loss. She is growing well, big healthy. Ready for a second round of clones. After, I will let her sign in a bigger airy pot. Thank you for any suggestions 🙏

Leaf burnt edges One leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).
