Yes that could be a problem and solution. Search the forum.
I don't know why you guys have to be so difficult.
I found this from another post:
Water when the chop stick comes out of the soil clean is a standard I hear often. Or purchase a moisture meter until you know the requirements of your tree.
From this thread
www.bonsaiempire.com/forum/basic-techniq...-bonsai-help?start=0 (I'm discarding the water meter discussion since 1) I don't have one and 2) users seemed, at best, skeptical of its effectiveness.
How "deep" does the chopstick (or wood pencil is more likely in my case) get inserted? To the base? Mid way? Just below the surface? Where do you check - near the roots? At the edge of the pot? Somewhere in between?
If my chopstick is returning dry between waterings but I'm still getting the gnat problem, is something wrong with my soil? Does my pot need more drainage?
I found this one (I think you wrote it leatherback):
Watering plants in the coarse substrate that you have here is a bit different from normal potting soil. It hardly spreads the water in the substrate. So in order to get the whole rootbal moist, you need to use a watering can with a spray nozzle thingy. All the surface needs to b watered.
I have my ficus (still) outside in the gardem (Except for one I defoliated). They get rained upon every few days. THey do no tmind a lot of watering. THey do dislike continuous water-soaked roots. Water more...

I see advocating generous watering, but I'm not sure it applies so much to what I'm dealing with, since that was a plant that was getting water once every 2 weeks and needed catch up. Also, as far as I can tell I'm currently over-watering...
I found this one (also by you leatherback)
So if the soil surface dries out (You will quickly learn to tell: It changes color, adding a few drops to the surface will show you straight away) you water.
Emerging into a tub of water is one way. I prefer using a watering can. When watering, give so much that it drains from the bottom of the pot. That way you know the whole rootball has received water.

This seems most relevant, except for here, you suggest checking the surface and then watering thoroughly, which is what I have been doing. So now I'm pretty confused: Elsewhere it is suggested you need to check below the surface, but here you say that if the surface changes color, you know to water. This has been my exact method (I think I read it on another beginner bonsai site), but I have arrived at the problem of gnats which, according to my research on articles (no forum posts came up in my search) is caused by soil remaining too moist.
You guys are so quick to brush off legitimate questions with the "I want to grow aerial roots on my ikea plant that I water every 15 days like the tag says" ones. Just searching is great, but there is so much information out there and so much of it is contradictory (or, as has happened to me, I'm just too much of a novice to grasp the subtle differences). Trust me, I get it, this is a community of experts that wants to discuss the finer points of something they love and have devoted time to and instead its mostly people asking lazy questions and then getting defensive when you tell them something they don't want to hear.
I wrote the question above because my research left me short, and I was hoping that someone with experience would be willing to lend a few minutes to steer me in the correct direction. Search is only useful when there is useful information to find. Its odd, because in my line of work, I spend most of my time correcting the opposite approach. People constantly come to me and say "Well, I read this online, and it looks correct, so then I read the statute, and that confirmed my suspicion, so I posted it to a few forums and people told me to go for it. Where did I go wrong?" I then get to spend my time explaining that while what they read seems correct from a lay perspective, an expert would have been able to explain a term of art, or that the statute they happened to read references another one which is pre-emptive, or any number of things. It always ends with me saying, "Please, just ask me first, it would have been cheaper for you if you spent an hour getting things done right, now we are going to spend 30 hours trying to fix this."
