I've got a small grapefruit tree that I grew from seed, and a number of its latest flush of leaves have their tips folded back on themselves. I tried digging around online, but I haven't seen anything that looks like this. Anyone have any ideas what's going on with these? They're currently sitting next to a south-facing window under grow lights, in potting soil (I know that's not ideal, but I don't know that I care enough about it to use/buy anything better at this point), and I've been using a granular citrus fertilizer on it.
