Hey all,

slowly developing with the lower leaves, new growth seems healthy and I see visible daily changes (not stunted growth).

Please identify, I put a topsoil of EWC on with my last watering just in case of a N deficiency.

Strange thing is, 4/5 of my plants are doing this, while my last one looks totally healthy and green on its first leaf set.

The second to last and the last picture are of the same plant/same leaf but 24 hours later (I plucked it to get a good pic while my light was on)
