I've recently picked up indoor gardening as a hobby after a few successes growing some houseplants.
I have a mango seedling that sprouted about 3 weeks ago. I just noticed that a couple of the top leaves are a bit weak looking and 1 is curling a bit. Just want to know if this is a sign of overwatering, fertilizer burn, or pests, and what I can do to fix it. My pot also doesn't have a drainage hole so I'm wondering if that could be a problem as well.
Update* It's been a couple weeks and the trees looking much better. I'm actually contemplating doing some pruning/tipping to encourage branching. It's about 10-12 inches now. I got a little lamp with a cfl bulb been using as a grow light. I'm in the process of building a set of shelves, and then I'll install some more lights, I bought an LED strip. The intent of my tropical trees is too turn them into bonsai, but we will see, perhaps I'll grow them fool size then give them away. Just wanted to share a pic of it too show the improvement.
