If you get the light as close to the tops as you can,and give the 20-20-20,not every time you water,though.Alternate with ph'd water every other watering.The light being close will make the nodes grow closer together and make your plants stronger!It'll help with the spindly stems,due to stretching. The more nodes,the greater the yeild.At 12-14 inches your ready to flower.Careful with the nutes! 20-20-20 will burn them up!It's the nitrogen in them that do the damage.That's why I say alternate with ph'd water.
