May 23rd, Day 14: today I swapped the reservoir with a freshly mixed batch of general hydroponics feeding schedule week 3 late growth. The fourth node was developed so I have topped it there, in an experiment of autoflowering topping. One strand of root broke off while I was prepositioning my air stone.
May 25th, Day 16: The plant is reacting very well to topping, and it appears that somehow I have managed to clip off the top and the node 5 fan leaf growths but the node 5 branch growths are still coming in so I will have a four branched top, it appears. I ended up retopping the plant at the 4th node.
