Hey sorry to say but that’s bud rot. You can to a plastic bag over that bud and they cut the whole thing off. The bag will help with not spreading any more mold( spores). To help in the future try and get the humidity down and also have an input fan and output blow fan.
Hope that helps
Happy growing
Bud rot/mold I had an auto malana bomb in a cupboard with not enough air circulation i had the same disaster Mate just get rid start again learn from your mistakes (with better airflow) Good luck pal 👊🏻
The bud i think is out, try to not propagate the spore in all the grow tent but at this stage they will be already there, cut it out of your grow area and take down the humidity as much as you can and improve the airflow
