Looks fine to me, stop hovering over your plant, you'll begin to see all kinds of problems, you'll know when a severe problems shows up, no offense, just trying to say don't worry so much, most the time it's nothing, seems to me that some gowers cause the problem by jumping the gun, assuming it's this, it's that, let the plant do it's thing....just my opinions, I mean no offense to my fellow growers.
