Can you trim before harvest?

Im new here, growing my first auto indoors (bettyboo). Just wanted to know if you can trim some of your leafs during the last 3-4 days to improve harvest? Thanks for your time

yes you can cut off any big fans and also trim some bigger sugars

You can but it will not improve your harvest by any means. I will sometimes pull all my fan leaves off the day before I am going to trim just to make the daunting task of trimming a shit load of weed go a little smoother and quicker. The leaves is where your plant pulls energy from to increase the size of your buds, trimming them off will have an adverse effect if your buds are still plumping up.

Thanks guys
