Yeah, I'm no expert but those leaves are showing some mild signs of nitrogen excess: dark color, downward clawing on fan leaves & an odd waxy coating along with some warping on a few leaves. Nothing too severe though if you stop feeding nitrogen-rich fertilizers immediately. But overall they look dang good to have been brought inside from the outdoors. If they're autos, make sure to give them a minimum of 18 hours of uninterrupted light every day...up to 24 hours a day. Your preference. Anything under 18 hours of light & they'll be stunted. They don't require a dark period but I prefer to give them one.
Definitely check out GrowWeedEasy.com since it's your first grow. They have info on every possible plant ailment & solutions for noobs. It's a great resource. Best o' luck!
