They come on later than my BG or Crystal and about 5 weeks is when they really took off and about that time is when the buds started to thicken up.
Well your making me feel better! I have to remember that at 5 weeks there just over half way there. Plenty of time for them to frost up and get fatter. I've noticed that they are starting to fatten already and like every grow I've ever done, I always look at them about this time of the grow and wonder if they will get bigger! They always do!
