Bro. Sorry but what do you expect.
Its cooking 16 weeks. That is why to long.
Honestly. If you had kept your light at the right distance at 30cm your bud would have finished up long ago and would of stopped pumping out white pistils as they do with photos. Harvest that man.
I don't know what you are looking for in the way of an answer but that needs to be taken down as the issues you said will only get much much worse
Good luck.
