spider mites

hi everyone i have just chopped one of my plants early because it died out of no where and i didnt know why... it was a really small clone and i still not sure why it died... All 4 of my clones are in 7th week of flowering and when i went to look at the trchomes with my 60x magnigying scope on the one that had to be chopped early and i saw a spider looking insect crawling around on the trichomes!!!! it was actually pretty cool looking... but anyway does this mean my other plants have them also because i dont want the other 3 to die because they still have a few weeks left.... thanks

if you have 1 you have more. they reproduce very fast. they lay eggs, so just when you think youve killed them, they show up again. they can go dormant when it gets cold and come back to life when warms up. if you catch it early, you can get it under control so you get a harvest. you really dont want to be smoking spider mites do you?
