Your plants all look really good! Don't worry about the one stretching, it has already started the pre-flower stretch, where plants can double in size in a short time. The others will probably follow soon!
I do see some leaves at the top tacoing a bit, this is probably because the temperature is very high. If you can lower the temperature, your plants will be even more happy! But if not, don't worry too much about it. Enjoy the grow ✌️
