If its not the damage from bugs that it looks like it is, does that stuff on the leaves wipe off ? I ask because I know some foliar sprays especially if its heavy doses will leave a residue on the leaves that looks very similar to bug damage.
Nice.... Is it not hot in there with that open wing ?
They look nice starting out. If you think they look small its because you only vegged for 7 days.
I bet it would love some plain water for awhile. That pot in the background, whats that white stuff on top the soil ? The leaves on that one look like they're N toxic.
