What to do?

Those red dots look suspiciously like spider mites - the scourge of the grow room - but it's hard to tell from the pictures. I've never seen them so early if that's the case. They are absolute buggers and will destroy your entire crop if not eradicated. Potentially this might be the best time to catch them - plant is nice and small and there's nowhere to hide. IMO, the plant is still weeks away from flower, so screw the neem oil or organic products and go straight to nuclear warfare. SMC or an insecticidal soap. Don't wait - you need to sort this ASAP. You can increase the humidity in the short term with a humidifier or turning off your extraction fan, and decrease the temperatures. They love high temps and low humidity. You can put diamataceous earth on the soil as well to prevent anything hiding in there (you can even foliar spray it this young). Then use a decent preventative such as a silicon additive with their feed and a foliar spray such as Cannacure moving forwards to keep the leaves healthy. Good luck! Kill those little f*ckers!
