First hydro grow, running into some problems

So we've started our first hydro grow, its an ebb and flow set up. We got the plants first as clones and they are only about 2-3 weeks old.

Some of our plants have brown spots on select leaves near the vein, and one of them has a leaf turning yellow. I dont think it is a watering issue, but Im not 100% certain. Ive done soil before but not hydro so maybe it is a problem with the neuts.

Currently weve been flooding the basin every four hours for fifteen minutes or so. Its about 20-30 gallons of water and we added a micro nutrient about a week ago, but we probably didnt add enough.

Any comments or tips would be appreciated, thanks.
