May 6 Day 11 of Flower. When I lifted the lid, I noticed that the water level was down considerably. I added 10 litres of water, nutes and Cal-Mag+. I didn’t feel that there was a need to encourage root growth, so I didn’t add any Rhizo Blast. I had to cut through roots to separate 2 plants so that I could move 1 plant to a corner site. I did this to allow for better light penetration. I may not be done. One plant is a bit behind in growth. I may take it out of flower and put it back in veg to use as a new mother. This is the most vigorous growth I’ve ever had. If things continue like this, my first DWC grow will be a major success.
