Massage the part of the stalk where the bend is, to losen it up, repeat if neccessary...
When it is losened it will bend more properly.
Until u get it to the point wher it will bend w/o creasing the stem too much, tie it up with a stick next to it, or some shit.
The correct way (that I know) to do this is to massage the part of the stalk where u want the bend, do it over the course of a day, 5 or 6 timesds until it becomes so lose that it will just fall in the direction u want it to go. It's called Super Cropping. Look into it for more details.
Just leave the burnt part of the bud on,
... If u burned ur nuts would u cut em off right away,
or try and let them heal?
Burning a plant in veg stage, u lose a leaf,
no big deal, almost like burning your hair off,
chop off the singed part and move on...
Do it in flowering=big deal.
Cutting buds, unless it's completely off the plant at a stem is going to cause more stress...
