Looks like you could use more time with those...they dont look mature at all. I'd say keep feeding it nutes for another 2.5 weeks then a week to 10 days of only water. What nutrients are you feeding them now?
For the bugs you can use hydrogen peroxide which is cheap and most have it at home:
If this doesn't get them all you could sprinkle diatomaceous earth on them. This is very cheap also and highly effective just sprinkle on top of those bastards.
- Mix one part of additive-free 35% hydrogen peroxide with ten parts water
- This will give O2 to you plants which the roots will love
- This will kill any beneficial organisms in your soil
You best kill them before they turn into flying things.
Have you noticed anything flying in your plants?
Also after you hit them with the hydrogen peroxide let the top couple inches dry up and don't keep it too wet. Moist conditions makes them thrive.
As for the smell..you can use sprays, incense etc.. OUTSIDE of your room. Or you can grab a small tub of ONA gel and put it in front of the door of the room your plants in NOT right near your plants. You wont smell anything anymore.
Unfortunately I have found some flying small flies... I will try to buy the hydrogen peroxide tomorrow in the pharmacy - hopefully i will be able to explain it in english to dutch phamaceutist
