Critical Purple Auto Flower

First time grow, has been about 7 weeks since I started growing. There are two others but they were started after this one. I did break one branch off not sure it that will cause an issue. Currently in a 4 x 2 x 2 but just ordered one twice the size. Currently, it is under 200 Watts Led. Order another 150 with the bigger tent. Thoughts on the branch outside of losing that bud spot? Using half nutes but this plant has some nute burn not much, I don't think it likes the nutes.
