Big top buds bottom not so much ????

my plants are almost ready to harvest. the tops and colas are nice and full but the bottom and lower bud sites are really scrawny and airy. can i top them so the lower sites get more light and hopfully get denser? how long should i leave them after toping ?i was told to only leave them for a day or two? what would get me the most yeild ? thanks for any info!!!!

Chop the top colas when they are ready, leaving the bottom budsites more exposed. Who knows how much time it will take for the bottom buds to finish developing. Maybe they will fatten up nice, but I wouldn't plan on them filling out too much. But hey, you never know.

use under lites they work well (cfl globe they make them in red or blue you will need red )put those on the bottom and ur nugs will grow fat!! you will get 30dercent more on your yield as well
