Tiny black but scarce bugs.

Think its thrips, despite you calling them gnats. Gnats fly, thrips hide underneath of leaf, could be huge problem. When i met them first time, i noticed at start of flower. Ladybugs and few natural predators sorted issue, but my harvest was 20-30% lower than i would expect. Sort it asap, have sticky traps all around grow area as prevention. Good luck !!!

Pests usually leave marks on the plant. Spidermites don't run fast, so you can rule that out. Thrips get black when they are older and can run fast, but you'll also see little chewed areas on the leaf surface. If there is no damage the bug probably isn't anything to worry about, but an image is essential to identify. There are lots of helpful bugs, so you want to ID them asap so you know if it's best to leave or kill them, but plant damage is the 1st thing I'd look for before panicing.

Hi, you can get yellow sticky traps. They don't cost much and help against pests. When the insects stick to them, it's easier to see exactly what is crawling around. Good luck with the grow!

Hey 👋 You still have no reason to worry, because if those critters are quick, they are very likely some kind of predatory mites. They would even be beneficial for you, as they remove serious pests from your ladies. Nevertheless, you should keep an eye on them and your lady. If you see your leaves curling or notice any signs of chewing on your lady — then you need to act, and quickly.

IMO It’s very likely you’re seeing thrips, not harmless soil critters—those tiny, dark, quick‐dashing insects match thrips behavior more than spider mites or fungus gnats. They’ll bolt across a leaf when disturbed and hide in crevices. Thrips can stunt growth and scar new foliage. Keep monitoring, but getting ahead of a small population will save you headaches later. Good luck!

Sounds like spidermite.
