I have 4 other blue widow plants 1 week from harve...

Hello @Dabz420 ! No matter if you see mycelium or not thats bud rot ( botrytis ). Cut the infected bud and lower the humidity by increasing the air flow with a fun and by a slight defoliation or you may risk to loose them all. Happy growing ! 👊

Hi @Dabz420, sorry to say this, but you're having a mushroom invading/killing your plant. Google for "Botrytis", I think it's that particular species. Hope this will help, keep us up-to-date and happy growing 👊

Its difficult to say anything with just a few informations. the leaves of the plant look crinkely and bit crispy and not quite healthy. i would say you got russet mites. the only one who can say that for true its you i let you a link for self diagnose on a helping site..........https://www.growweedeasy.com/cannabis-symptoms-pictures... i thinks its a kind of mites

hey dabs, just go ahead and harvest that bud if it's dry then its ready, even when it's on the plant. Your plant is drying itself out from top to bottom, so be careful how long you wait from now. Check those trykes everyday because they can go ripe overnight. Basically your plant is at the end of it's lifecycle and it can behave wierdly while trying to make flowers, like drying itself out, yellowing of the leaves, it's that sort of thing.
