A low flop cbet isn't necessarily bad depending on your strategy but it's weird to see such a low double barrel (turn cbet) after low flop cbet as I assume your flop cbetting range will have a lot of equity in draws and value hands to bet again with. It seems either you have a really polarized cbetting range and are checking back a lot of medium- semistrong hands/draws (which you should be cbetting at these limits) or you're not barreling thin enough on the turn.
This doesn't conclusively mean anything's wrong btw, but it's something I'd look into. First look into what hands you're checking back on the flop... is it just pure air vs people who never fold, mid strength hands you don't know what to do with, etc, then look at hands you're betting on the flop but checking on the turn, maybe 2nd pairs or some kind of draw.
I think at the micros turn and river cbets are hugely important and people give up way too much because they see their opponents call a lot on the flop and saw them call down with 2nd pair once so think they never fold. A lot of these guys have such wide calling ranges on the flop that even if they're calling down semi wide their range is just so much wider that barreling in the right spots is awesome. There's spots where I bluff the flop + turn knowing I won't get many folds but they're folding like 60%+ of rivers, or if you're paying enough attention you'll notice some people check/call 80% of flops then check/fold 80% of turns. Also because of their wide ranges you can bet thinner for value, especially in position, betting flop + turn with 2nd pair then deciding what to do on the river is standard in a lot of situations, especially in position... you can sometimes even think about doing it with 3rd pair against guys who check call with any 2 overcards.
Obviously these are just ideas you should look out for, not things you should blindly implement, it's really hard to get a handle on even when you know what's going on so post a lot of hands asking questions about this when you're unsure, even if it seems basic like should i cbet here (list factors you're considering and later street considerations) is this a good spot to 3barrel for value/as a bluff etc. Also take a ton of notes, like every showdown, you want to know as much as you can, especially the hands they show up with you wouldn't expect - what their flop calling range is and how they play it on later streets, how they react vs a check back/when checked to, how do they play their river range when the check/call and turn gets checked back. Even things like noticing they limp then fold OOP to a 5bb iso raise but call a 4bb iso raise can be really significant (or slowly creeping up and realizing they'll limp/call a 10bb raise 100%).
Oh also I wouldn't worry about folding to steals/3bets too much if most of the opponents opening and 3betting are nits (found this was the case at the micros, especially at a rakeback site), obviously make correct adjustments to guys that are doing it a lot, but when you open CO with AQ and get 3bet by a BB with a 4% BB 3bet it's fine to just get out of the way. You will notice people swing totally the other way though and be opening SB 80% when it's folded to them and stuff, crush those fools (actually they're probably pretty smart).
