Beginner needing experienced eye

Hey all. My first grow of anything, ever. I have gotten the hang of growing pretty well, considering this is a home built system.
Somehow I have fumbled my way to this point and would appreciate any advice.
Just a couple of spots here and there but nothing I am/should be concerned with, correct?
Thanks in advance.
7 days since 12/12 switch
5x5 Tent with 2 x 315 SS LEC's.
GH Trio Equal Parts / CalMag / Silica
PPM's = 450ppm (Any higher and they throw tips) Drops about 40ppm over 24 hours.
PH drifts in a range of 5.6-6.2
I have been adding back a 500ppm nutrient mixture to keep the water levels and PPM's up.
I can provide more/better pics if anything needs clarified.

Not unless it gets worse. This could just bad genetic function in a leaf. It could be bugs. You can't do anything about the genes. If it's bugs you might have a big problem. Don't spray anything on the leaves unless you're trying to kill bugs, but even then it's not a good idea. Remember it's intended to be consumed. Look pretty good actually.

I inspect all the leaves I trim off and sometimes the plant itself under a high powered loupe.
I have not seen anything but a couple drain gnats though. I will double check tonight to be sure.
Thanks!
