i know there is a similar bug that resembles a spider mite but their quicker and bigger but only eat bugs i cant recall the name though il have to get back to you
i mean if you wait too long itll start to degrade the thc but depending on the strain i wouldnt know too much but i remember i smoked some purple kush before ina blunt and i didnt even feel it at all some are just a bust i guess
usually it will just depend on genetics for 90% of the time others take a bit while some grow insane. usually the first 5 weeks are slow on any genetic but it should pick up soon. just make sure you have a fan and are able to get fresh air to cycle in often and most important is being patient
