First Grow Box Questions -- Leaf discoloration

This is my first attempt at growing. I got some seeds from a friend's batch, and started them off in soil. I have no idea what strain they are, what gender -- I only know they're not tomatoes. Last week I moved them to hydroton and setup an ebb/flow system. I am looking for help with understanding the leaf discoloration symptoms I'm seeing.

Please send me your suggestions. I want to learn how to do this right. I'll post some closeups of the leaves. I'm at about 80F and 35-45% humidity in my box, and about 50% recommended concentration of Shultz 10-15-10 plant food.

Any help will be greatly appreciated.
