obviously you have a good light thats why you have a tight internode space.. tou can try to rise the light if you want them to stretch a bit more, but you’re fine..
i would definitely clean this girl up.. you can for sure remove all the smaller branches that are in shade in the lower parts of the plant.. divide your plant visually in 3 , and remove everything thing in the first 1/3 of the plant.. hope it helps ;)
