Calcium or other deficiency?
TripleCcannabisstarted grow question 5 years ago
Is this a calcium deficiency? Brown speckles on only 1 leaf but some other leaves gave mildly upturned edges. I had what I think was a magnesium deficiency a week ago and added calmag.

in any hydro media, you should be giving calmag throughout grow because hydros lacking on calcium and magnesium. do not stop giving calmag for a while from now on
RastaMouseanswered grow question 5 years ago
Yeh that looks like a cal/mag problem. Dose slightly higher with your cal mag and keep an eye. All should be good.

Its a DWC grow and my ph is between 5.7 and 6.4. Do I need more calmag then? This brown spotting want present before. Just yellowing on the borden of the leaves. So I think my magnesium deficiency evolved i to a calcium deficiency but i am ot sure. Thus is my first ever grow.

If your pH is correct (6 for coco or 6.5 for soil) then I would say calmag was the best way to go. Check your pH is correct and don't over or under water. 🌱👍

Yellowing of leavesI usually grow Outdoor, easier
I don't add any nutrients to the plants. Only organic things during the grow, if something is missing.
The soil is a mix of compost and earth with nutrients (stuff you buy for vegetables).
When you are talking of ppm, what is it about ? Nitrogen ?Week 1
