gnats. they aren't really harmful, more of a nuisance but still try to take care of them. you can use gnatrol or mosquito dunks I think along with yellow sticky traps for the flying ones

The first 2 pics are not RAs. Fungus gnats have a longer body similar to a mosquito. But that third pic looks suspect. Try to get clear pic and we can help you ID it.
Use this link to help get a positive ID also. Yellow sticky cards to catch flyers will help.
Its not unusual to have both. RAs kill the roots. FGs are attracted to the decay.

Fungus gnats or WINGED ROOT APHIDS???

Get some yellow sticky traps, put one up by the light and one down on top of the soil. Then you can catch and identify them once stuck to the trap.
If it is fungus gnats, use Microbe Lift BMC root drench. Thats the most bang for the buck BTI based product currently on the market, better value than mosquito dunks or gnatrol. It does take a little while to work as it only kills larvae leaving the adults to die off but if you have a sizable infestation and if you need to run another 3 weeks or so, you should try to mitigate them as best as possible because they end up stuck all over your buds and thats really depressing.
If they are root aphids and the situation is advanced (usually is if you see winded adults) then you are likely witnessing what appears to be a magnesium deficiency but it's actually damaged from the crawlers eating your roots.
Fungus gnats are not harmless as they can vector diseases such as pythium (root rot) so if you have floor drains or sink drains in the area, you should dump a couple tablespoons of bleach in them every now and then to kill off the larvae in the P-trap. Prevent having any standing water around, especially runoff from your plants. Thats a fungus gnat breeding ground.

If they are gnats, and you are growing in soil, put 2-3 inches of playground sand over the soil, Then use bt or spinosad in your waterings and spray the leaves as well. You can also use sns 209 if in veg.
A good varied ipm schedule in veg will save you a lot of headaches.
Root aphids can be a bitch I hear, but I've been lucky enough to never get them. About the worst I've had have been gnats and the occasional thripe. Both easily dispatched in veg.
