The most common reasons for buds to blast is a sudden change in growing conditions-this happens often if someone buys a plant in bud and brings it home to conditions different from where the plant was growing previously, and lack of humidity. How is the humidity where the plant is growing? Do you use any air conditioning that will dry the air out?

Other things can cause buds to blast as discussed previously. Smoke, ethylene gas, and the plant becoming too dry are other possibilities. Did the plant get too dry recently?
