I'm growing a lot of species that I've never grown before this season and I'm starting to notice species definitely take a bit more TLC that others. This definitely makes sense since all species come from completely different climates and geographical regions. For example, I'm experiencing what I believe is an iron deficiency due to high pH in some of my plants. Some are doing fine while others are exhibiting foliar symptoms. My thinking is there are some species that are used to growing in lower pH, poor nutrient environments. Has anyone else noticed this?
