Reminds me of Wind Whipping. FWIW. For some of my earlier crops, I take 3lb coffee cans and cut out the bottoms and place it around new transplants. I leave them there for about 2 weeks so the plants have a chance to Get a Grip FWIW. I had a old Frenchman tell me to "shaka de table" everytime I went past my seedlings. This is to help develop stronger stems. An oscillating fan also helps. Byron
