my twins.......2 plants from1 seed cool pic.

what do u think will it live or not

That's just one plant with two growing tips, nothing special sorry.

Yes it will live.

what dos that mean? will it have more bud

A plant can only support x number of growing tips before yield flattens off but as this has split of it's own accord and you've only the two tips it should be fine.

I'm guessing you basically topped it somehow. All the means is instead of having 1 main cola (main stem/big bud) you will have 2 main colas. Do some research with the keyword "topping", and you will be surprised. I reccomend doing it to a few more of your plants at this age too.

Its actually good that it was done that early in it's life. It'll support its buds a lot better than if you had done it later on the line. I do it at that age too.

And yes. There will be more bud.
