New growth reverted back to one leaf. What's wrong?

These og kush were fine the started losing a leaflet till it's down to one.
I have the same issue with a cutting of dbl skunk. Any ideas?

Og kush

Probably just needs more light.

Looks like it's trying to reveg.

They're getting the same amount of light as the other kushes and others too. Only three of kusg a doing it and one skunk. The other 3 og a good, all dbl skunk are good, all purple kush are good, all godbud and black are good.

The leaves were curling last week when I pinched those off. Like a cocoon was inside but nothing, and there were about ten curled leaflets per plant.

I would drop my ppms 15% across the board and resume in a couple days after that straitens out. I get that when I'm pushing them to much
