Spots on my plant : ( help plz

Hey what's up everyone. I am having a small problem with my plants I'm not sure if it's somethig to worry about or not. I don't know why it's doing it so hopefully someone here can help haha. So I planted my seed about 3 weeks ago an it's for pritty big sence then. Everything has been fine so far exept I left a couple days ago an now I'm back I noticed there is some light spoting on my plant.
as you can see it's not real bad bit I just don't want it spreading. Or even killing the plant. Here are 2 more pics one of the whole plant
an one of the other spots.

One more thing though I recently got some clones from a despensory an this didn't happen untill I got them. Could that be something? Get back to me thanks everyone

thats going to happen...its normal and fairly common, from sprout all the way thru flower (even more so then). as long as its not just consumin ur plant and its just a few leaves here and there, nuttin to worry bout....plants look great, keep up the good work n good luck!

Give it a few days and see what happens. Could turn out to be nothing. If it gets worse however you should consider any problems created by nutes, if you use any. How does that section of the leaf feel though? Does it feel dry and crispy?
