noob advice need help

i am 2 weeks into my grow and the bottom 2 leaves are going slightly yellow and are going dark brown around the edges also really small brown spots are appearing on them leaves the top leaves seem to be ok ? any advice is welcomed

Is it the bottom round leaves or the first set that looks like pot leafs? My round leaves browned and are about to fall off but I'm not concerned because the rest of the plant looks very healthy and bright green. So take a look at the rest of your plant, you tell me. Is it a problem?

are you using nutes? what is your water ph? what soil are you in?
