im a newb and this is my first grow

ok so this is my first grow i have the seed in a 5 gallon pot its about two weeks old and have 4 to 6 leaves but today i notices the end of one of my leaves was like torn and had holes what do i do?

Sounds like either clumsy fingers or somethings having a munch when u not looking. Check ur plant for anything living under the leaves, and mist it regular and check the pot too, like if its got a lip at the top something could be hiding there. I kill anything that moves in my grow room if i see it, unless its a spider, they can be better to have around as they could be helping keep a few other bugs away and spiders dont eat plants. Just dont let it set up home on ur plant either. Its good to have a fly paper or 2 hanging around ur room but its unlikely a fly thats caused that type of damage. So keep an eye on the floor. Check for slime trails cos if you see any its a bastard little slug and they wait till its dark to come out. I hate them
