nutrient deficiency??

That’s pretty minor. I think if you keep a good feed/water regimen she’ll be fine. When there’s a lack of nutrients available to the plant she starts using energy in fan leaves to continue with new growth. In the grand picture. Those leave that are affected right now will be defoliated in few weeks time anyway. I wouldn’t stress your plants are nice. Now if your whole plant had this issue and it kept getting worse then there’d be some cause for alarm but right now I think you’re good.
