Just noticed the lower leaves on my summer purple sprouting broccoli seedlings are turning yellow. These appear to be the cotyledons so is that normal? They are under a gro-light (18hrs), watered from the bottom and given very light fan breeze 2 hours twice a day. Each now 2-3 inches tall. I plan to transplant out next week. In a SFG some say one per square , some one per 4 squares? Any other general advice?

Your seedlings are of appropriate size to move outdoors. Remove the yellow leaves. Plant them a little deeper than they are now planted and give them some balanced fertilizer. They should grow out of the problem.
Broccoli will do nicely when planted one per square foot.
