I know, I know. I really didn't think the plants were rootbound because they are so small. But then, that's probably what has kept them so small, eh?

The new pots have perfectly adequate drainage, and no, I had never tested runoff pH, but I will start doing that now.

I feel fairly sure these plants are ruined, so I am starting a couple of new ones. My first problem was that I didn't do any research prior to starting the first ones, and I made a bunch of mistakes.

The nute mix was 1/4 strength 18-18-21.
