Ok so you started your flush then.

I looked as chose as I could at your pictures and it looks like you underfeed them. When in flower and expecialy late in flower the plant's requirement are for more P&K and less N if you stoped everything the last 3 or 4 weeks then you missed the change to pack on weight to your buds. If you can't raise the light then you need to try to tie the plants down or maybe place a screen over the top fo them and push it down so only the buds poke through and reach the light.

Hey there is always the next grow but at least this time you can get something and that is way better then many people get.

Happy growing.
