I dont see evidence of spider mites at all. I've seen spider mites kill a ten year old pine tree that was 30 feet tall in only a few months. You'll know when you have them. Just stare at your plants for a minute and if youll see them. If you squeezed a seed and this stuff came out that was kinda milky or wet, thats evidence of a seed. Youll know you have hermes because what looks like a bud from a distance, will actually be a collection of seeds up close. Bud rot is quick and will spread overnight.
If they are hermes, Id say its time to kill them. If you're not sure, Id wait a little. If they were my plants, from the time they were vegetative I would have been feeding them cold pressed neem oil every 4 weeks or so, sometimes more frequent depending on the strain/time of the year. August/Sept is definitely spider mite time, so be wary. If you do have spider mites, neem oil will kill them and will also kill/prevent mold. If you've got bud rot, that means the rot is coming from within and spreading out. Neem can stop this from occurring before hand, but in my experience, is less helpful once rot takes hold.
Invest in some neem oil, wait a day or so and you'll know if its bud rot or hermes. As for spider mites, any ol magnifying glass should help discover those little suckers. Ive discovered by trial and error that lady bugs find them a nice snack.
Edit: I dropped 15,000 lady bugs in my back yard last year (overkill I know) to kill an aphid outbreak in my garden. When they had consumed most of the bugs in my backyard in only a few days, they moved onto the field directly behind my house. For the next month, you could see thousands and thousands of lady bugs on almost every blade of grass in every yard on my block. This year, we've had no aphid outbreaks near my property. I was at my neighbors house yesterday and saw that his sunflowers have aphids. I was shocked, until I noticed the hundred or so lady bugs per leaf on the 30 or so plants in his yard. Lady bugs rock! Don't ever underestimate them. They're my first choice on most outbreaks. Inside, outbreaks are extremely uncommon for me, as I keep my grow area spotless and isolated.
