Defoliating bud size

You need more phosphorus for your buds (if the nutrient section in your journal is accurate). Blue diesel is a sativa strain, I believe, so the buds won't always get as fat but the colas will be very long and dense. Again, up the phosphorus by a lot and keep the nitrogen down where it's at. I recently picked up Humboldt's Secret Flower Stacker for this purpose.

Nah man, its fattening up well, it fattens up the most in the last couple of weeks, nice timelapses btw, you can notice the growth from one to the other. If you put both running side by side and look closely it becomes obvious they are getting fatter. Nice plant.
