You're plants are probably okay.
That being said, to provide a better answer, it would help if you would start a grow journal (yes, even this late in the grow). What's your lighting and how far above the plant tops? What nutrients and how often?
To fatten up buds, I add Humboldts Secret Flower Stacker to the nutrient mix. Since doing this and switching to LED lights, it's been nothing but fat dense buds, even on smaller plants.
Good luck
