It looks burned up to me. The only time I've ever experienced bud rot was with an outdoor grow and none of it showed up at the top of the bud. The butterflies laid their larvae on my buds, it hatched and caterpillars went to work and I got bud rot. But the inside of the bud turned brown and it would crumbled and break away from the rest of the bud into your hand when you touched it. If this is the only one you've got in what looks like (??) a scrog, doubt it's bud rot or they would all look like that. You need to give more info on what you've got going there and what/if you've given anything to your plants or done anything different lately to it. The more you explain, the better chance you have of figuring out what's up. I've never seen that before, but maybe somebody else has. TWW
It looks like budrot to me and especially if it's squishy. In my outdoor grows it did start at the top. If I were you I would remove it in case it spreads which it can do overnight. Hopefully I'm wrong and it is indeed just burnt. Sent from my iPad using Grasscity Forum
Only seen rot outdoors myself but that makes me think of it... ...better to ask @vostok Homie will help
Yes it is. Cut it off just below the rot area to avoid spreading. It can happen indoors just as easily as outdoors and especially in warm humid weather. J
you need to rip it open and check with ur 30x loup'e attached to them trics should be some flaky black spots //spores perhaps some webbing too like spider mites..? the spores are everywhere nothing can be done about that but often growers, more this time of year set off the conditions that mold just loves ie. 15c plus and 75% Rh reduce watering and improves venting often helps I have been known to dip my live buds into a 10% bleach / tepid water solution should turn all suspected mold to mush that you later pick out once dry good luck
When you harvest make sure you do a H202 wash. It will kill and sterilize any spores. You dont want that to spread when drying/curing.
