Please help!

Yes, definitely a male flower and not a swollen female calyx. And while we are being honest, 3 pictures taken from long distance does not help answering this question. At least you had one picture that was useful, but three similar pictures as to the first one, would have been far more helpful. Seeing the issue close up is vital and posting pictures of an entire plant from a vast distance does not help anyone, least you, if you are wanting effective answers. This seems to be a common occurrence with question askers - asking "is my plant ok? then posting pictures taken from 6 feet away and is a constant source of frustration for those trying to offer help, as no details can be seen. You do however get 10 bonus points for taking the pictures in "normal" light! I would also suggest sweeping your tent, all that trash on the floor is good for insects and/or mould and fungus to get going. What you do now with this plant is up to you, either get rid of it or try and pick all the male flowers off, but even one missed flower will release enough pollen to fertilize hundreds of calyxes, so you will have to be super vigilant. Hope this helps,........ Organoman.
