Aldo90answered grow question 4 days ago Aye pal. If that's your first attempt, I want to say well done for the set up you've got is brilliant. The issue is clearly the light has fried the tops of the plants causing loose buds. Also, you've not put which nutrients you are using. Could be some issues going on there also. With that system you'll be smashing it in no time. But that light especially for autos in that sized tent max power 75% and I'd be cautious still.
