Light too close?
Anetxu420started grow question 4 years ago
So These are 17 days old. I have been watering them with ph water 6.3-6.6 keeping it under control. I am growing on super soil so only Tap water but yesterday I added 2 cc of calmag and ph 6.4. Today they are some yellowing almost like cal mag def or too close to light?

Looks more like a calcium excess wich blocks slightly the uptake of potassium, iron, magnesium, and manganese.
I would move the light closer to see if she spends that extra calcium and magnesium. Moving it further away may end up extending the effects and toxicity of the calmag additive.
Hope it helped good luck growmie.
And stay lit.

You got some yellowing on the bottom leaves between the veins, probably a very slight N deficiency.
The yellow on top looks like regular new growth to me.
