I'm noticing light green growth on all my new plants. The odd thing is that they're all in different mediums. I have one in coco soil & I'm only feeding GH nutrients and 2 in different super soil mixes. For the coco & super soil mix #1, I've been feeding it a mix of RO water + dechlorinated tap water (my cities water is very hard). For super soil mix #2, I've been feeding it straight RO water.
Does this new growth look normal, or perhaps is it a CalMag deficiency?
