Lemon Balm help

Lemon Balm help

I bought two lovely, robust lemon balm plants maybe two months ago. They grew even more robust and were really nice looking. A few weeks ago they started looking really lanky, despite my pinching and the plant just didn't look as good. Then the leaves started turning brown from the tips, and I cut the plant back drastically to remove all the brown spots. Now some of the new growth is turning brown too. It got a little bit of the leftover water with tomato food in it over a month ago - I don't think it's burning from that because I really didn't give it much. Any ideas? I also picked up a chamomile plant on a whim and it's turning a bit yellow. Any hints to keep it happier? Both plants are outside on my east-facing porch and I'm in Zone 9. We had a few really cold nights (almost down to freezing) here in Florida a couple weeks ago, but I brought all my herbs in for that. ________________________ Also, an update on my aphid problem with my peppers. I sprayed them down with a mixture of water and dishsoap and it killed all the aphids, but I think I went overboard because now the plants look half-head. They are droopy, the leaves are discolored and they are looking pretty sad. One of the four plants has baby peppers on it, the rest haven't produced anything yet. Would I be best off just digging up the 3 really sad looking ones or do you think they'll make a comeback? (Can you tell I'm new at this?)
