Your roots are to the stage that potting up to a larger pot would be appropriate. The roots are not pot bound yet but I would cut through them vertically from top to bottom in several places about 2 inches deep when potting up. I would not consider bare rooting them. Orchid mixes are usually mostly fir bark and come in large size pieces or small. The smaller size I think would be OK for your tree. Most houses in the winter with the heat on become very dry and tend to draw the moisture out of the foliage. Do what you can to keep a reasonable humidity and rotate the containers to equalize the light. You will need to water about once a week with enough water that about 20% drains freely from the container. If your trees show signs of wilting between watering, shorten up the watering frequency slightly. If available locally look for citrus labeled fertilizer that lists the minors on the label. Watch for aphids or scale and if found take the containers outside, and spray thoroughly with Neem or horticultural oil. Al

Yovan, one of the two cuttings did not make it, mostly my fault learning. The other cutting is doing very well. No where near the size it should be. I neglected it for 1.5-2 years due to countless life obligations that I could not get away from. June/2017 it was in such bad shape every leaf was curled and dried up to a crisp from not being watered for over a month in very hot temps. My family and I were forced to vacate our home due to an asbestos contamination and were unable to return. When i finally was able to retrieve my tree's and did my best to bring it back and have been taking overly good care of it since. It has completely come back to life, dropped all its old leaves and has grown all new and some. We are now in a new home and I am hoping this spring it will take off and make up for my lack of taking care of it for years! I will try and take a picture of it this evening when I return home.

It is normal for a tomato plant to root all along a stem that is buried. I am assuming from your use of the term "chitted" that you sprouted the seed before putting it in the growing medium? Personally, when repotting, I do not add any nutrients to the medium. All that your baby maters need to be fertilized with is . . . . water! Unless there is something going on that we don't know about, your NAR should be just find. Bets

You have to up size your pot slowly to get the fibrous roots you want by the time your tree in in its final pot regardless of your soil mix. The 5-1-1 mix Is the best mix for tree root health regardless of how big the pot is for any size tree. It is also the citrus trees best friend. You can't go wrong. My tree are all going in ground outside so I don't want a fibrous root structure . I want a spreading root structure. That is why I went from a 1 gallon container to a 5 gallon and to a 30 gallon and into the ground. By up-potting in small jumps you will have a fibrous root system that will let you lift the tree out of its pot and clip any root/roots that are wrapping up until you need to up-size to a larger pot. Let Mike add more. He has 10 years more experience than I. My goal was to make my trees grow like a weed from very small to too big to handle in one year instead of 3 years as most do. I used bucket lights and a hot/light box to achieve this. Most citrus'er find it's to much hassle. It did jump me from seed sprouts to 9-12 feet of linear twig growth per tree in the first year. 1 year old Sweetlee tangerine tree from seed sprout in bucket lights then grow box over winter. Inside the buckets with a bucket light over head. The grow box came next What I did wrong for potted citrus. 1) I up sized the containers way to fast with to big of jump in pot size regardless of mix. 2) My soil mix is very very heavy that requires vacuuming excess water and aerating often. 3) Grew trees from seed when I should have bought grafted trees I was wanting. What I did different was the strange lighting systems that jumped me forward 3 years of growth in one year.
