I just got over this problem fk'n problem! Webs on the buds, that is a large outbreak!
What you need is 4 cans of bug bomb and neem oil.
I researched the spidermite and it's life cycle so I could effectively arradicate the problem
This is how it works
Bomb on monday, bomb on thursday, bomb on sunday, and then bomb on thursday.
Now the beauty of neem oil is, it fk's up the bug reproductive organs so they cannot reproduce, so it is not a quick solution, it stops the problem from comming back.
After the bomb on monday use neem oil on the leaves of the plant, then a day to rest, and so on.
The problem will go away quickley this way, and then use neem oil solution on your plants once a week, this will cause any insect that eats ur plant to become unable to reproduce.....Prevention is the key, and I had to learn the hardway.
Hope this helps.
Neem soultion: I use 2 tablespoons for about 44 oz of water.
Use hot water add neem oil and slowly stir in dish soap until the oil is broken down and a few bubbles are present, and that is it.
