pic 2 looks like spider mites, also your pics 3,4,7, look like nutes, iron or phosphorus. get some florotmite, and spray your plants, those mites are very quick to destroy. then you may want to start buying a few different mite killers , cause they usually get used to the chemicals and if you keep changing them up, they will go away. never spray them during flower, always in veg...with the nutes, i would flush them next time you feed cut the dose in half, some nutes are notorious for nutrient lock out cause there so dam good. if you get the floromite (on ebay) you can buy it for 25 bucks, it last for about 3 weeks, wich is what you will need to get rid of those frickin mites, ive had them a couple times but you get used to fighting them and not panicking after awhile. these are the same pests that kill roses and other plants right outside your door. so dont get flustered, be patient take your time but spray them quickly, if all you have is cold water it helps! good luck.
