Hey Laxguy420,
What do you mean by bud chunking?
Getting them bigger and compact?
If so,
1. Get rid of lower brances from the plant, thoose branches will never produce good buds,
2 Remove some lower nudes from all of your branches, these nodes will produce smaller buds.
3. Remove (fan)leaves below that does not get any sunlight,
4. Raise your PH from 5,9 to 6.3-6.4 slowly, nutrients that are needed for flowering have a better uptake.
if you do these things, more enegry will go to the upper branches which results in bigger and compacter buds.
goodluck growing :)
