1st grow

Hey there, they look really happy, and healthy. I would say you've got a slight nute burn. Really nothing to worry about. Sometimes, I prefer to see some slightly burnt tips like your girls just to let me know they're really sucking up some nutes. Might want to ease up a bit for a feeding, check your pH, and TDS. It looks to me like you're pretty close for optimal absorption, and like I said earlier, those burnt tips tell me they're taking up some nutes. One thing I noticed is the 23 hrs. of light. That really seems like a little to much to me, especially for fems and/or photos. Really even for Autoflowers. You might want to consider running like maybe an 18/6 on them to give them some recovery time. They do look nice though, so just some thoughts for you. Happy flowering!✌️
