A question from a fellow grower:
Three days ago, I noticed one of the WW leaning more than normal. When I tried straightening the plant, it broke off at the soil line. That’s when I noticed that the stem looked like it had been constricted and looked like an hourglass in the middle. Now I’m down to two plants. Tonight, I was watering and inspecting and again noticed that my NL was leaning. Closer inspection again revealed the hourglass figure on this plant, and also on my remaining WW. I’m following the same feeding schedule I’ve been using successfully for over a decade. There is no strange colorations or disfigurement on the leaves. I always use fresh soil for every grow. At the end of the grow season, I take the planter out and scrub it down with soap and water, followed by a liberal dousing of bleach. A quick rinse and we’re ready for the next grow.
What can be causing this problem with the stems being constricted like this?
