This is black cherry punch auto Not sure why it has deformed new leaves. Old leaves looks fine!! This is my first time having this issue Humidity is high

all your leaves have something funky with them, so far. Hope it grows out of it or at least is 100% functional. Some oddities impact the outcome and some do not. This could still be nute related, but there's enough funkiness to lean genetics as the cause. Duck-footed leaves or wahtever it's called, they have a strain specificaly bred to display this weird leaf trait. This would be an example of an oddity that doesn't hinder the plant and some people like due to comaphlage nature of it - doesn't necessarily look like a weed plant. Or, that humbuldt monstrosity with the wierd ugly leaves, lol...i'm spacing on the name of that strain and likely got the duck foot term wrong but something to do with a duck bwahaha. these superficial things are not something i dwell on. ther are some genetic issues or viruses that severely impact the outcome. usually you can see it in reduced growth early on, but some can be tricky and grow seemingly fine, only to give shit flower. if it looks like it interferes with photosythesis, get rid of it. Nowadays, i don't risk any of my flower canopy being a dud. I always plant 150-200% of what i need so i can throw out the maybes and the weak before final pot transplant, so it's not much added effort or space needed to do it. Yeah, occasionally it'll be a great plant but why risk it? i don't want to play games with 4 months of my time.

Some plants just do this randomly for no reason. Usually it will be the odd leaf here or there, but in the main, the plant will grow and flower just fine. It is not humidity related, just a random mutation.

I've had growth like this due to PH fluctuation, should just outgrow itself...although I'm a new grower also! Good luck :)

No 1 answers cause most only answer for points for prizes. It's a mutation mate. I've had it before. Been it's a new shoot. It's keep pushing up and it'll grow out of that. Time. No big deal. I know it's an auto. But. Keep pressing on. You might get a lil stumpy mofo
