Wow, your buds look good considering what you just said!

The top buds are less mature than the bottom buds? Never heard that happen before considering they're closer to the light.

Do you still have mites?

Usually with a pure indica or indica-dominant hybrid you won't go longer than 11 weeks (and a lot of sativas don't go 13 weeks). If the top buds don't look ready yet, then don't take it down. I still say cut all your lil buds off that look ready, dry, cure and enjoy. It's about time you got something off these last 4 months

Looks like you've learned a bit from your mistakes, and that's the most important part. Get rid of those pests, one plant per container, and happy growing, Cana
