I have ten hot pepper plants in pots on my screened patio. They were grown from seed and potted up twice to where they are now. Potted w/MiracleGro Potting Mix.
The growth was fine for the first few months, nice big leaves, etc. - then, once they started flowering and producing yet more new growth, the leaves on the new growth stayed smallish and started curling. Some fruit on the lower part of the plants are growing but it seems most of the new buds/flowers (located with the curly leaves) aren't doing very well - dropping off, etc.
Some of the lower, larger leafs are dropping off and have what looks like some light rusty/brown spotting .
What causes leaf curling/flower dropping on peppers? What should one do?
