I mean for the time it's been it looks fairly normal. Some don't stretch and get big till late. But for now do you know the ppm and pH you run in the water ? Yes co2 helps but it not a giant change, add one if you want. The wrinkles is from heat stress.
Hi little bit of advice. Use some micropour tape to hold your stem back together instead of wire. It's the stuff that is used to tape slings and bandages. This will stretch as the plant gets bigger. With wire it will cut into the plant as it grows. 👍
