I'm hoping one of the experts will come along and help. I'm posting several photos of different plants, not all have the same problem but it may be related. I'm taking soil in today for another test. Our soil pH is slightly over 7, water has calcium carbonate hardness in excess of 300ppm, not chlorinated. I garden organically in transition to become certified. I use Espoma Bio-Tone at the recommended rate after transplanting or after seedlings have true leaves. I also add greensand at the recommended rate. I have never had this many problems all at once. In addition to the chlorosis, the caterpillars (various but mostly diamond back moth, cabbage loopers and leaf rollers) are driving me nuts. We've had wind and rain making it hard to spray but I think I have the caterpillars under control. Weather is hotter than normal, highs in the 90's, cool front expected to hit Thursday night.
Problem Overview:
Various species stunted growth, yellow leaves some with pink tinge in a row of green plants. When plants are dug up, the roots are healthy. Here is a photo of normal broccoli (yes, it has worm holes) and chlorotic broccoli side by side.
