is the reddish , purplish, color on the seedling just the color of the plant or is something else happening .The little ones have been under the new light almost 2 days now haven't grown much, assume they just getting used to the new environment.
Naw, looks good. I've had a couple have this color at first. It never seemed to affect them much. Either a slight sunburn or slight overwatering maybe, but nothing to really be concerned about.
