Whatever it is it seems to be fine, ive had this tree for 3 years now, the second picture i rubbed some neem oil on the trunk and it went back to white in the first picture after a few months.and is pretty vigorous right now, except it has some leaf burn from over fertilizing last month

Why do you think it has a problem?

I'd be pretty confident that the white part of the trunk is the rootstock and the difference in bark colour of the 2 different varieties is showing up now. JM varieties are often grafted onto standard JM seedlings. The difference in colour is one of the reasons bonsai growers try to avoid grafted trees.

ok so the bonsai farmer that claims he gets original stock lied to me im guessing....So its not a kiyo hime but a mixture of multiple JM's?

Yes, sort of, a lot of "fancier" cultivars are grafted on to plain Japanese Maple root stock as some are very hard to root. Kiyohime is very easy to root, but they are grafted a lot too. So what you have is kiyo grafted on green Japanese roots. The graft doesn't look all that bad.

but that bleached color will never go away, is there a tree paint that i can do to cover it up?

Never heard of tree paint, but why would you want to paint it? Your tree is starting to form mature bark, which is a grayish-white or a grayish-cream color for most of the Japanese maple cultivars. Eventually the entire tree will have that color to it, the green color is only present on young trees and new growth. The root stock is probably a little older than the scion so it is barking up now, eventually the scion will too as you can see it starting as white "splotches" here and there. Both parts will be the same color and you will hardly notice it (the graft).

Um, the white bark is DESIRABLE for a maple. It doesn't develop until the tree gets a few years under its belt. You don't want the bark to remain green. That's a sign of immaturity, which is not what bonsai are meant to convey. This "discoloration" isn't a bad thing. It's part of the growth process for Japanese maples. It will spread over the trunk in the coming years. The rootstock is older than the scion (top part) grafted onto it. That means it will change soonest. The process is already beginning on the top however.

Leave this alone and for God's sake don't paint the tree.

This tree has two different sides. One with a browning bark and one with a pale grey (sediments on the?) bark. I think watering is an issue and this can be solved easily with a tooth brush and vinegar.

+1 for what @Mellow Mullet and @rockm said

as an aside, i would place that tree lower in the pot. It is too late to do that now, so I would add a layer of sphagnum on the surface (especially around around the trunk) for now, and adjust the placement of tree when you repot at the appropriate time of year. Vendors sometimes pot trees high like this to expose roots, because the idea of exposed roots is something that people often have in mind as a valuable feature when they come to the hobby. It is a valuable feature, but this tree is too young to be showing those roots in my opinion.

I would want as many roots as possible emerging from the same horizontal circumference. You currently have that circumference exposed, with a dozen roots emerging from it. Because it is exposed, new roots will not emerge along that same horizontal axis (roots tend to emerge-and-survive below the surface of the soil). By lowering the tree and by pruning back some of the roots when repotting, you can encourage new roots to emerge where you want them.

I love kiyo hime. Like koto hime, they produce very straight growth, but also back bud vigorously. If this were my tree, I would consider this trunk-line (see attached) for the future, or something similar. But I would not do this before that left branch (=currently your main trunk, it seems) thickens the lowest portion of the trunk a bit more, helping to conceal whatever is happening in the area of the trunk that currently and rightly bothers your eye

if that lowest portion continues to bother you in the future (i.e. in 3-4 years from now), possibly because of swelling, I would consider grafting (thread graft) more kiyo hime below the 'graft line', creating a multi-trunk tree that will conceal the area currently in question

just thinking out loud :)

Nope. If you take a brush to that "discoloration" and scrub hard enough to remove it, you will take the bark off down past the cambium and seriously injure the tree. That color is NOT sediment. It is bark...

Hmmm, looking at the very first picture...
lt looks like a white sock, the left portion of nebari is 2/3 different from the rest of...
But I might be wrong, sure.

You can apply diluted lime sulfur to maple trunks, it can help make the whole tree white more quickly. Usually done while dormant as it is too strong for the leaves. Mach5 has posted on this.

Well, yeah. Half the trunk has more mature bark, the other half is still developing it.

So when I first purchased this tree 2 years ago I wanted to do a root over rock maple after a few years with it and cutting back alot of the branches, it used to be styled as a broom I don't know if I want to still go that route, i will definitely be repotting it next year, and i was thinking of up potting it to continue the growth
