Blue Widow

@Mrs_Larimar, no I never found out. By the time the buds were cut and dried I could hardly tell which bud was affected! I would assume that bud had just started to dry out and die.

@Dabz420,Ok keep us on track

@Stick, thanks for the reply! I've had plants infected with botrytis before but this isn't what's happening with this plant. The bud looks healthy and tough the only visual difference to any of the rest of the buds is that it is yellowing. It's very dry, someone had previously mentioned that it may have finished flowering and be drying out and dying or its been under-watered but the plants are watered daily and it's only midway through week 7. I'll add a picture to this diary when I update it next later in the week.
