Does my plant have bud rot?

No I can't see any bud rot there, and I've had it a few times usually on my big fat main colas its no joke man. The way I've always spotted it is it shows up as a yellow ish sugar leaf half way up a main bud, and when pulled lightly will come away with ease. If you bend your cola at that spot you will see it as a fuzzyish grey white mass which is soft wet to the touch, at this point its damage control and the best thing to do is cut, harvest early any main cola buddage and dispose of any infected plant material asap. Be careful doing this though as any disturbed bud rot areas will be putting out possible spores, so you need to cut and dispose of as carefully as possible without to much man handling which will eliminate the chance of it spreading. But if you do happen to spot this, chances are its in more than one place and you'll need to up your game. Shedhead out!
