Newbie - are they looking ok

I'm a newbie and was just wanting some feedback on how these are looking at the mo. I have a couple of leaves in the whole batch that are looking out of sorts but the rest look ok. Just wondered why a couple of leaves look like this but none of the rest do (thank god !)

Looks like you might have some nute burn. But other than that look pretty decent man.

Thanks for the reply.
Is the nute burn due to too much nutrients ? How come its only affecting very minor leaves, obviously I don't want it to affect more leaves but just curious, as trying to understand as I go along.

Might just be older leafs. Ive also seen leaves that touch the substrate do this. I wouldnt worry to much about it, just make sure your not overfeeding her (yes too much nutes is a bad thing). Looks very healthy other then a few leafs id say your doing just fine.

Thanks for the response. Guess I maybe panicking over 'minor' things but just want to make sure.
