White spots under leaves

The plants that I have are starting to turn yellow on all different parts of the plant. I don't think it is a nutrient deficiency because the discoloration is happening all over the plants and in no pattern, (i.e. top down) I looked on the underside of the leaves and noticed a bunch of little white spots close to the veins of the leaves. Plz help with this, I have never had this problem and I'm not sure what to do. Thx

 

Have you checked for spider mites?

 

These would look like what? If they are little black things then I havn't seen them. I am almost 100% positive that whatever the little white things underneath the leaves are, are what is killing them. The white things look like eggs of some sort. What are the indications of spider mites?

 

Little white things under the leaves. White spots visable on the leaf top from the mites sucking the juices.

 

That = it exactly, read about something called neem oil? And started spraying yesterday with an insect spray that is supposed to kill mites. Anything special I should know?

 

Yep, spray every 4 days for two weeks. As the eggs hatch you have to kill them before the next batch hatches.

Death to all mites!

 

Neem oil is good for mites or trips, I try to save some money and use a nicotine spray (works just as good). Nicotine is a pesticide, if you don't know.

Boil water, let it start to cool. Take some skoal (chewing baccy) in a teabag and dip it until the water is a gross brownish color. Add a tablespoon of dish soap (this makes it so any remeaining pasts can't breath). Spray liberally. Do this atleast 3 times, about ever 3-4 days, then spray your plants with plain jane water. Only do this in veg/early flower.

DON'T LET THIS SOLUTION COME IN CONTACT WITH YOUR SKIN, THE NICOTINE WILL ABSORB INTO YOUR SKIN AND MAKE YOU SICK.
