Folliar feeding during veg was definitely a bad Idea. It wasn't with nutrients but damage was still done obviously. I guess its a bit hard to guarantee feed schedule. Everything is a little different, specially a micro grow with cfl.

Yes. Besides those rusted leaves the rest of plant looks well. The pot is heavy so it won't need water/nutrients for a little bit and it grown to 7" tall now.
