1st time Space Bucket Blue Mystic AutoF

You have actually answered your own question. If you feel the tops are too close to your light you will have no choice but to super crop them to save the buds rather than let them get burned. I will warn you that with an auto if you stress them out too much they can hermie on you. Next you can remove all tiny buds sites and fan leaves from the lower 1/3 of the plant. This will direct more energy to the upper buds that are receiving the most light. Good luck hope this will put your mind at rest. Next time try some indica dominant strains they may be more manageable for your grow set up.
