Never grown these before. RedTailForester was kind enough to send some wild Sonoran tepins seeds. The plant was alive and well until about 2 weeks ago. Now I get yellowing on new leaves and the odd large leaf. I am actually quite diligent to make sure it is dry before watering. I have a few varieties going this summer and each need are on a different watering schedule... all done by hand by me. It has received the same small amount of ferts that my St. Helena George, Florida Wild, Piri-piri, and Wild Brazil has received. None of the others are yellowing. What are your opinions?
