Tip curl/Ram Horn Question

Ok so I bumped up my feed on 4 girls the other day and I over fed a bit. Started to see burn so I was gave a small flush and going to back off. Well now a couple girls have ram horns on the big main fans and I was wondering if this was from the flush. It has that heat stress look without the full leaf curl. So I know it's not heat stress and I know it's not over watering transpiration. I've heard that plants sometimes do this when you cut nutes abruptly. Just wondering is that true or do I have another problem I need to look into? Thanks guys

I mean obviously when you over feed this can happen but none of these fans show burn. Only burned the very top few fans close to light.

Turned out to be just normal burn. Took a few days to slowly yellow and burn. GG#4 took it the worst, she's far right. The one in question was the Bubba kush on far left. Everything is flushed and back on previous feed.

Looks good
