Not sure if these are genetic or deficiencies?

Give her some CalMag, as looks like a molybdenum deficiency

When my cabinet temps got too cold my plants started to purple. I thought I had a deficiency but it was just too cold. 64-68°f is to cold. From my understanding you should be 72-84°. Im a newbie but they look cold to me.

Looks like ph issues. Probably to low from how green it is and the minor claw issues. Give it some ph'd water and transplant to a slightly bigger pot.
