What is happening here?

I'm having change in my plants color.
If anyone can point me to the right direction.

Looks like bug damage to me, I'd spray her with spinosad.

It's yellowing, with brown lining. I think it may have to do with the nutrients.

Here's a better picture

What's the medium? What's the ppm on the nutes? Is it just water sprayed on them?

The tiny white spots on top of the leaf look like tell tale spider mite damage spots. Without nutrient info and medium/grow info, my best guess on the brown color would be lack of water or over fertilization. Just a guess though.

The white spots are water spots. Roommate thought it was a good idea to water the top part of the plant with the same water that has nutrients. That should explain the white stuff.
The nutrients are GH Flora series, floragro 2-1-6, floramicro 5-0-1 & florabloom 0-5-4.

Im thinking of changing the water all over.

How much nutrients goes into 2 gallons in veggie & flowering cycles.
I may need someones recipes for nutrients

maybe this one just googled
