Hello there, couple things that can screw floral development, but I'd expect it to show on both if it was what you were feeding or environmental Looks very similar to whay I'd expect if I had either given her a light leak (photo) or over stressed, started flower but stressed back to veg. I wouldn't expect it from a auto as both should be effected, I'd have to lean towards a genrtical weaker tolerance to stress. Can't handle the heat get out the fire.
I'm not sure though 🤔.
