What is this marking on the leaf?

I love all this info! I had only thought of the positives from the tap water after the stabilization of the PH but you're right, tons of other things in it too or killing off of the good bacteria! I did add that water with the intention of changing it out completely this weekend to fresh RO with new nutes. I may continue to try to use tap just to top off simply because I hate going to the store and filling up my jugs. I think I may invest in some small RO system in the near future. I probably spent at least $50 on water in my last grow.

How do you water? Could you have splashed some of your feed onto the leaf?
I can't count that out, it is a definite possibility. This is my last grow using my coolers as reservoirs, I am switching to a RDWC next time using 7 gallon buckets so I can change my water on the outside of my tent. I make it work right now, but it's not the easiest method!
