10 day old seedling under 18/6 led lighting. 250PAR. Watering every couple of days. Soil is Happy Frog mixed with Perlite. Did some research but couldn’t find an answer…has anyone seen this before?

I’ve had that happen. Larger plant though. I added nitrogen. They greened up. On that small of a plant I would be careful. Dilute in your watering cycle. Too much nutes and you can burn the plant.

Had to get a soil pH meter but looks to be about 7.0. I am a first-timer at this. It also appears that my water is 7.5 so I will work on getting that down to a more reasonable pH. Thank you for the guidance.
@jsl yeah high pH will lock out iron. Bringing the pH back down to healthy ranges will fix the iron deficiency.
