yes,mix nute to the amount of gallon of water that you have for res,I believe you said you have a 3 1/2 gallon reservoir and I believe you should go a teaspoon for every gallon of water also Im thinking your babies are three weeks old so you should have at least ppm reading of 800 no more than 900 ppm,remember ph is a vital issue so i would set my ph at around 5.2 to 5.5 optimal nute intake would be 5.2 u get the most cal/mag intake in those range that what your deficiency is,they are being lock out also iron dissipate quickly in hydro so, since your not using tap water you have to have cal/mag+ .Im also new to this hydro grow but i've been doing test runs with my bubble cloner alone with a lot of reading hope this help
