The 4 dwarfs

Got my new tent and ventilation set up! 36x20x53. Now they have plenty of room and no more defoliation. Time to see what these babies can do. pH is staying around 6.5 runoff and I'm using pH 5.5 going in. My ppms each jug of nute water are around 950 and coming out in the 550s so they are using a lot of nutes. I feed twice a day and change the water each time. For 4 plants I use 1 gallon a day. These Royal Dwarfs are awesome. They stay so small, well might have to do with my pot size too. My pots are only 6 inch. The roots are coming to the surface now. I am using self watering pots with the area below for water. My roots have almost filled the whole area underneath. I add 2" of water under and top feed twice daily... It's a lot of work but they are beautiful. Oh and it's 4/20! 4/23 Noticing burnt spots. Still feeding twice a day. Might be from light burn or something else. Will keep a close watch.
