Help to Identify what these Deficiencies are with my plants? Also Any Tips on plant training these girls would be well appreciated!

Where is the damage in relation to your fan? Those markings kind of look like wind damage. It looks very minor though and not something to really worry about unless it's getting worse.

Take a look at my recent thread. What I thought was deficiencies was in fact placement of equipment inside my tent. I had similar damage and it was a result of placement of my heater, light, and fan burn. It wasn’t until I got down and close to the plants that I found the culprit. Very similar damage.
