I would plant it up to a larger container. There seems to be a lot of concern on this forum of overwatering Citrus, but as long as your tree is healthy, the soil drains well, and there is heat and sun, you will not risk overwatering them. Curling may be a sign of under watering (your container looks smallish, I would not think overwatering would be an issue). Your tree looks fine though.

I was thinking about moving it buto I read that it's not a good idea when it's blooming. It's not curling like the pictures I have found id under or over watering. They are just curling tip down almost making an O shape. They don't feel brittle or dry and none of the leaves are yellowing. I'm just really new to this and didn't know if there was a reason for the curling I needed to worry about.

Thank you for the response on the potassium, do you have any suggestions on what to do to remedy the problem. I have fertilized with an 8-3-9 citrus plant food, but like I said am new so any advice is appreciated.

Your fertilizer does not seem to be the problem because it has a good enough ratio of nutrients. (Many on this forum use Foliage-Pro 9-3-6 fertilizer.) Your problem may be the pH of the fertilizer solution. It should be between pH 5.5 to 6.5. If it is not in the range, the tree may not be able to absorb potassium well.
Get a cheap pH testing kit - the kind used to test the pH of swimming
pool or aquarium water. If your tap water is above pH 6.5, add enough vinegar
to adjust it to about pH 5. - 6.5. You will only have to add give or take 1 Tb/gal.

Thank you! I will definitely do that. I really hope I can get my tree to its full potential.

I actually have a tester I found and if I am using it correctly my soil PH in the pot comes out to 5.6 to 5.8, checked a few different spots. I'm not trying to be dumb I just want to make sure I'm doing it all right.

I posted pictures of the fertilizer and the current PH of my soil in previous comments. I live in South Texas so the temps have mostly ranged from 65 at night to about 80 during the day and as far as sun they get atleast 8hrs of sun. I water when the soil starts to feel not moist about two inches down, it has good drainage so the roots aren't soggy nor are they dry. When I bought the plant the leaves were curling so I may be doing everything right and its just still recovering.

I think you hit it right on the nose..It's good to see that you are providing all the right stuff and you are very south..I'll bet with your care and your regimen that all the new growth since will look ten times better..Please give it time since you are not loosing branches and keep us posted....I can't wait to see what that tree looks like in a couple of weeks or two.
