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?

My last strain of white widow would do that regardless of what you gave it. Sometimes its genetic.

Watch the new growth, as it gets older if it darkens up in a few days, its genetic and you dont need to do anything. If the light green lasts past the new growth stage, then it may be a calmag issue.

The coco is most definitely going to need calmag as a rule.

Good luck man! Hope a few others chime in to give you more options.
