First time grower here. Growing out the one seed that sprouted out of my decade+ old bagseed stash. I am in week 8 of flower, just flushed three days ago, and I noticed some leaves turning black. I pulled them out and some rotted looking bud came out. I quickly cut the whole Bud off ( no damage in cut stem) when disecting the bud I found a white oblong fuzzy thing that looks like an egg case. After closer inspection I found 3 more buds with the same issue. All had the offending white thing inside. I was growing outdoors but lately it's been cooler and damp, so suspecting bud rod I moved here inside and put a fan on her. I don't see any more problem areas, yet. I ordered Trifecta Crop Control overnight, hopefully that helps. I was wondering if anyone can tell me for certain what this is? Bud rot, or some type of bug? And is any of it going to be salvageable, or is it a total loss?
