Flowering issues

I am 3 weeks flowering into my first grow. I have a lot of buds forming everywhere. I have 3 plants 2 are from the same clone 1 is from a different clone. This is the one I am having issuse with. While 2 plants are very strong the 1 I have a problem with seems to be unable to support it's bud's weight. The stalks are leaning almost to the ground. Is this an issuse? Should I support the stalk?

support by all means necessary.

well if im understanding this correctly from how your saying it, if your internodes are spaced enough in an area, use twine or even a tomato plant cage and tie it onto it for support, if outside, inside get creative also, some wind resistance for it in the early stages builds a stalky stem, gets that nice tree bark effect and feels hard as bones, almost lol, makes branches able to support better as well, less bending around when you move them, just the leaves will shake and mild branch movement means awesome staying power for the bud sites.
