For awesome grow results. Try a very diluted seagrow foliar feeding but only between 7 to 10 am and then after 5 pm. As the receptors underneath the leaves are then open to take in nutrients And try burning a small candle near your plants . The candle produces Co2 which the plants love. But please dont put the candle too near the plants. The heat may scorche them. I had a 7 cm grow for a week. Where i normally avriaged on a 3 cm grow.
