wow....that woulda been a killer outdoor grow. you are going from a plant that was experiencing full sun from most directions to a comparably weak fixed light source. if you have not trimmed them, lst'd them or anything than you probably should now. how bushy are they? ideally you should have trained them earlier but you still can the new growth. i would trim everything not getting good light after you set up so your plant can expend energy where needed most. bigger, denser, frosty'r nugz.
more importantly though, remove your hoods/reflectors from your lights hang your lights vertical, i think you would yield more than from the overhead. i don't know what kind of space you have but basically put your nicest plants or whatever will fit between in the middle. i would prolly arrange somthin like this
2plants
Light
4 plants
light
2 plants. This way you will get light on both sides of and good amount on outers.
seriously what good are your best budz on top if there all burnt to chit? and double seriously, i think you will pull much more yield this way. Those plants are way to big and your ceiling is way to close. hoods/reflectors trap waaaay too much heat or focus it. by hanging vertical you plants can grow MUCHO closer. your plants will take care of you. your plants will grow towards lower hanging vertical lights from all imagineable directtions. nestled in there ya dig.
