I have eight plants growing. Three are dark green, bushy, and look fairly healthy. The others are lighter in color and their growth appears sort of stunted.
Some leaves have shown the yellow coloring and brown spots. I have removed and destroyed such leaves. Suspecting a fungus, I ordered neem oil and will treat all the plants. Does this seem like a rational diagnosis on my part?
