I think it looks fine man. There's gonna be some fat budded colas. It's alright if one or two of the lower leaves die as long as the buds and their leaves look healthy. If you see it progressing up to other leaves you know you need to do something though. I think of anything you're over feeding, make sure you do a feed, feed, water, feed etc. Or something similar, they won't like getting nutrients every single watering 👍🌱
