Flappy half blades on leaves??

I got 3 plants, week 5 of veg. Ph was 7.0-7.3, and was getting signs of magnesium deficiency. I had overfed bc I was told I'd be gone for 4 days and had just transferred to 3gal pots from red cups 2 days before. Anyways I believe the 9 day stretch between watering helped bc the burning tips has stopped.
HOWEVER, I now noticed my one plant has flappy/lazy halves of leaf blades. Another plant has a spot that looks...deflated? Any ideas?

Looks like plant mutation or leaf defect - plants don’t necessarily grow picture perfect.

Just don’t get too careless with feeding ( overfeed ) either.

Phew that's a relief, didn't know such a thing existed haha
Yesterday was the first in 9 days, and it was only 8oz each with epsom salts and vinegar to lower ph. Was enough to do a small circle closer to center. Tested just now tested and it was reading 6-6.5 roughly using rapitest pill powder+water, color chart. So I watered with big bloom about 6-7oz each around the outer perimeter since she was so dry. Dry enough I saw after one pour I needed to do light dribbles the whole time lol.
