I concur with the others. They look very hungry. If it was me i would pull the yellowing leaves as they no longer serve any purpose and block light. I dont know what medium youre using but a dose of recharge and/or a compost tea would probably help alot. Once you get em healthier use some bloom nutes. You should be fine though. Weed plants are amazingly resilient. Ive had photos before that went almost completely yellow in veg from lack of anything and still got em back with a little tlc. You got this. Good luck! Oh btw, purple stems look like could use some calmag. These autos seem to need it more, especially under led lights. Hey, keep us posted on progress. There are some good people here that can help ya alot. I still ask for help sometimes. A forum of minds is better than 1.
