I definitely need to replace some of my potting soil because it's full of salt bulidup lol. I thought this might be true, then read something that made me question it, now I am sure. Radish death mystery/ squiggly weak leaf mystery solved.
Many things grew decently or even very well! But my oldest pot has a plant in it that it turning literally purple???? in places from phosphorous deficiency despite being recently fed phosphorous. There are white crusts from all the water buildup and it seems I'm just gonna have to a)replace potting soil moderately regularly b)water only with filtered water or c)likely both lol.
This is a big deal though, this solves a Large Persistent Mystery that has caused me to really kind of feel incompetent and bad at gardening for a while.
