Leaves showing “wrinkles”

Perhaps the light is too close? Leaves will curl up when they're not getting enough moisture to help trap it in. But what I see is short plants with yellow marks, this could be light burn. Try dimming or raising your lights?

I would stop giving any nutes for at least 2 weeks or more until flowering, just give her plain water for now.

Too much water or nitrogen. I get it it often, because I like to keep them humid and spray a lot, some strains are tend to be more like this than others too. If you let medium to dry out and do right cycles , all will be good when she will grow bigger and evaporate faster .. All the Best !

Some plants do naturally have those deep ridges between veins

Could be too much water too ,anyway they loook ok 👍🏼

Looks to be a bit of over feeding to me. Best to link your diary to your questions so people can help answer you more efficiently. Best of luck!
