At day 15 started adding nutrients at 25% strength for 3 days, then up to 50% strength for rest of week. Growing well but not very tall. bout 5 inches. Will be low stress training (90 degrees over) on day 21. Have listed ferts as General hydroponics but cannot get any maxi-bloom, so i will mimic its NPK (5-15-14) for full grow adding more bloom ferts as the plants get bigger or as (necessary). we will see.
