This will lower the amount of bud you woulda got and now those lower branches are gonna be the bud producers now "not the large branchs you had to suport and produce bud". Long as you still have some good bud sights you should be fine. Goto member they can sometimes double in size when they go into bud but most will slow down and put the growth into bud production and wont grow much more taller.. But yeah topping when going into flower is not a good idea and this also might "shock" your plants. :rastasmoke:
