sound like it may be starving for oxygen, if the soil is holding too much moisture it will harm the roots

Cotyledons turning yellow is normal don't worry about those,

Id use 1/4 or 1/3 strength nutes to start and see how it takes it.

it is possible that it is oxygen, add some 3% hydrogen peroxide to your next water, add about 3 tablespoons per 1/2 gallon of water. The hydrogen peroxide has an extra oxygen molecule and will help supply the root system with more oxygen.
