I’d recommend extending the flower time.
Also maybe try and bend some branches so they don’t touch the light and get burnt. I like to use metal hooks in the Grobo with some gardening wire. I hope this helps! Some people also physically bend the stalks in a technique called super cropping, this link might help: https://2fast4buds.com/news/benefits-of-super-cropping-autoflowering-cannabis-plants
