How old are they? I usually do not start my feeding until the roots have at least started to reach for the water. Pictures would be great help in identifying the problem. Yellowing can be caused by lots of things if they are turning a neonish green/yellow and splotchy than it could be a MG def, in which case CALMAG will solve, or if you do not have any calmag you can use epsom salts at about 1 tsp per gallon of water. Could also be an N def.
