Weight Difference

My two juicy fruit (sativa dominant hybrid, thai origins I think) are done with 49 days of flowering now. They don't really have amber trichs but their leaves are shriveling up and dying and the site where I got em (BCSeedKing) said 7 weeks to finish. My main concern is the difference in weight, not so much the difference in potency. Any guesses what the weight diff might be? The buds are pretty light and fluffy, I think this strain is probably better off outdoor or I just didn't grow it right.

keep it flowerin till it falls

imo,if its sativa dominate then you should let it go a couple more weeks.i think seed bank flowering time has to do with their fastest finishing phenos and perfect conditions
