Alaskan purple auto.

By end of week 6 and beginning of week 7 the plant started drooping. I was also out of town for most of the week and set up a drip system for the days I was gone. I assumed this was a water problem so I let the pot get pretty dry and then started fresh with water and no nuts. The plant bounced back for a few hours then the leafs dropped again. I also raised my lights thinking that might be the issue but that didn’t change anything.
