Hey there. Checked out the photos and the video and I don't see any problem at all๐. Does not appear you've hit a deficiency or toxicity and the girls are very healthy with a great green hue to them. Only suggestion is if you have more Veg nutrients to apply, I'd only warn to start low and go slow if you don't know how the girls will react. I hear of people waiting for a deficiency before feeding, but this seems counter-intuitive to me. I don't like starting my feeds on a deficiency. Whatever your manufacture's recommended feed chart says, I would personally start at a 1/4 to 1/2 dose just to test the waters... Monitor your pH and RO numbers to make sure things aren't going sideways with the new nutes, and you should be good to go๐๐.
Good luck! I know you'll be just fine๐
