Need help plz

Ok so unfortunately I don't have pics my internet is down and I'm using my phone for this but the flower point on my plant is falliing over not from wieght but something else about a cm of stem under each point has become rubbery and dead there's plenty of water if anything too much leaves are turning yellow around on fan leaves and bud leaves are turning brown

Rot / mold / fungus.... every plant?? if not yet it will be soon.. get humidity down if you can... too much water, you answered that yourself.. get rid of anything thats rotting... get that humidity down!

So...got any pictures of this phenomenon?
