Does this look like root rot?

My acer palmatum pre-bonsai had been growing well, but at some point the leaves started browning heavily from the edges inward. At first I thought it could be leaf scorching due to too much sun, so I put it somewhere else where it would only get sun in the morning and just a little bit at noon (just didn’t have an even shadier spot available).
Other than that, in bonsai class they said: β€œacer is a tree that loves humidity, and as a bonsai, it should be watered every day”… at the beginning I watered it fully everyday because the soils would always get dry, eventually the temperature started dropping a bit, and sometimes soil would still be slightly moist, so I would only spray it a little bit, assuming the next day it would get dry.
Anyway, my tree started looking worse and worse, so I decided to check the roots, took it out of the pot, rinsed the roots, they’re not completely dry yet, but I took this pic before deciding to repot. I’d like to make sure first.
2ft to light, direct
6” pot with drainage
Last watered 3 months ago
Ok so, it seems like I was panicking for nothing. After washing the old soil off the roots, they looked healthy enough to put back in soil (new soil)… I guess it WAS just sun scorching, and overwatering, the soil where it was DID drain really well, but I guess it was old enough and compact enough at the bottom, they it never dried out entirely.
Forgot to add to my last message. Roots almost completely dry here. I did see some white spots I thought could be root mealy bugs, so I treated them before putting the tree back in a pot.
Definitely pull back on the watering. Wait intil the soil is dry 1-2inches deep before rewatering
I’d say change where you place this tree
