There is something very, very satisfying about watching those buds form and then fatten up day by day, is there not?
Take your time though - go by the trichomes if you can. A lot of times the "due date" for the plants will come up and people will chop 'em, when the plant really has another good week or two worth of packing on weight in it. They can be deceiving!
In any case, y'all are doing great. Plants look happy & healthy, and those bud sites are gonna get fat indeed.
