question concerning lighting and bugz

what are a few signs of spider mites, i have 2 plants that just grew their 3rd set of leaves (3 leaves). and apparently little white spots means spider mites, my plants dont have that they just have like..some barely noticable kind of..scratch looking stuff on some of their leaves. idk if im just a paranoid pothead but im just trying to be careful

another thing, how important is the light cycle. like they get at least 14 hours of concistant light in my room its just i have to take the set up down whenever i leave the house incase my mom snoops around my room. i usually turn it on few hours before i sleep and right before i go to work in the afternoon. and then like the light pattern during the day is all fucked up sometimes they get like 4 hours during the day and sometimes 6.
thx

How important is the light cycle? Probably the single most important thing involved with growing marijuana! The photoperiod should be as dependable as clockwork! You can juggle around with your nutrients and you can water on a hap-hazzard basis, but the lights have to be on a regular schedual - the plant's life cycle depends on it!

 

DAMMIT!!!!! why does pot have to be so FUCKIN hard to grow!
