Heya! Looks like she’s looking for some calmag. The spots would be from a calcium deficiency and yellowing can be caused my a magnesium deficiency. Make sure your pH is in the correct range at 6-7 for soil and 5.3-6 for coco. Add a little calmag and watch for recovery. I always add 150ppm calmag to my feeds. Cheers and goodluck

That is magnesium deficiency. Add calmag, make sure pH is good and she will recover no problem. Easy.

I don't know why it turned yellow, is this normal? The pH is fine too. I raised the light to prevent burning.Mango Juice en DWC 40x40
