Seedlings looking great MassMom!
Are the seedlings in coco in the small pots? I wouldnt wait until they are completely dry as coco should be treated like hydro for best results. Sure, they dont want to be drenched at this stage but keeping coco moist is important. If you have the possibility to bubble the water before watering the girls, they would appreciate it alot.
There is different approaches in coco and i see you have alot of help and

allready from others, but different views of things can be good. Then just pick the ones feeling best for you and matching your grow-room. But for me coco should be kept moist atleast.
You go girl!
