I'm thinking it's a potassium deficiency.
Leaves are curling down, developing a very sickly looking form of yellowing on the outer leaf edges in addition to 'canoeing' upwards. I was just looking over the plant and watering when I noticed these little specks of brown-orange looking rust on a couple of plants. Not sure what it is. I just watered so I don't want to take a soil sample, but I'm willing to bet there's more than enough potassium in the soil, I was the one who added the potassium fertilizer. If it is due to a potassium deficiency it's probably due to a lockout. But of what?
What could the issue be?
