I have a young basil plant found as a volunteer that I recently planted in to a pot of miracle gro potting mix in a 10" pot. There's plenty of drainage. Now the plant has turned quite yellow and the leaves are very much upturned rather than flat or slightly droopy like a good specimen would be. You can look at the leaf from the side and easily see the bottom surfaces facing outwards.
I've noticed that my basil always ends up looking this way.... Any ideas?
