Hey, to me it looks like you sprayed your plants with something during when the lights are on. If so, you should never spray plants with lights on, always have it off. Nutrients burn leaves under the light.

Lime green mottling on leavesHi,
Still seeing mottled green on leaves, more visible on the first set. She appears to be growing well but I'm eager to understand whats causing the green mottling so I can head off any problems. I've been comparing with various leaf issues but struggling to find a match?
