Parsley Goodness

Since the passing of my basil plant, I have acquired two new plants to fill the...err... gaping hole in the vegetation section of my heart. One is a little pot of parsley and the other is lemon mint, which smells divinely refreshing. I have them out on my balcony since about a month ago and they are looking a bit scraggly at the moment. Pretty sure they need a more dirt and perhaps some nutrients. I really hope they don't decide to die on me too! The parsley is looking a bit worse for wear, but will write more about that at the bottom. When they first arrived, I couldn't resist adding a bit of parsley in my scrambled eggs breakfast. Here's what the deliciousness was about:

Nom nom nom!

For those who are better with plants than I am (which should be all of you), perhaps you can help enlighten me with a diagnosis? They are both out on the balcony that has an awning, so they are sheltered from the rain (which has been constant for the past 3 months, pretty much) and brutal sun. The awning, however, does not protect from the crazy heat + humidity though. As the weather gets very hot, I water them almost daily and let excess water drain from bottom of pot. Anyways, here's what's up:

Parsley

- leaves and branches turning pale yellow and soft

- there are a few small baby leaves sprouting (can't tell whether they are coming or going, hmm...)

Lemon mint

- edges of some leaves are black, and some leaves have dried up. Otherwise still alive and kicking.

Help us.
