lack of crystal

My plants had very by buds but I noticed they do not have much crystal on them. Now, after drying them for 3 days those big buds start falling apart I believe the reason is due to lack of sticky crystal.

Could anyone please help me to find the reason for the crystal problem, for the future grows?

Thanks for your responds.

Your problem is buds dont grow crystal meth. Lol

I would need to know specifics of the grow. But I am inclined to believe it was genetic.

Each plant is different, even from the same batch, I would not worry about it.
