Food for plants

Peppers started to fruit but aphids still covered all plants. We gave up spraying soapy water and ended up rubbing them with finger every single leaves. I gave them comfrey juice to boost. I also basil nettle juice because they look pale. Potato look all right but they have small black spots on leaves. What a smell! The plants on outside row were particuraly small and I gave them organic potash. I also gave potash to carrot, beetroot and cucumber.
