just tie them off when the buds get heavy,try to prop it up a little more,just a little ,if your concerned,put a little aloe vera on it and a piece of painter tape,you will be fine,that is monster cropping,that bend will become a big ole knot and give extra strength,like med said just put stalk in between fingers and slowly squezze as you roll it in your fingers,all your doing is lossen the stalk up for a bend,kinda like rolling a joint,just lightly roll it,you will feel it getting softer in you grasp,when i do it i roll it and repeat a couple days,most time it just start to fold by itself
