Thanks! That's going to come in handy. Actually it might already be useful b/c I think I might have some macronutrient problems (no big surprise being FL). I've relied heavily on composted manure so far as you can see at the base of the plant. The article really helps to identify the symptoms of each deficiency. That's one reason why I don't want to grow any rare cultivars yet... until I get some of the soil issues sorted.
This is a recent pic of my DC. You can see the yellow and necrotic stripe to midrib, although it is basically at the leaf tip. Reference page 18, fig. 13 of article.. "severe potassium deficiency". It surprises me a little bit b/c I also use some granular and liquid ferts regularly. The leaf just above that is showing signs of yellow around the edges as well. I thought maybe this was due to the seasonal change, but now I'm wondering. Thoughts?
