White On Leaves (PICS)

First noticed About 2 Weeks Ago Seems To Have Stopped, Can't Tell If It's Just Burnt Cause Of My Previous Set B4 The HPS Or What. Tell Me What You Think. This Is The Only One To Do This Out Of 9, But It's Growing The Fastest.

I had this happen once early like yours and it turned out fine.Kinda looks like the leaf has been bleached just like mine did.

you prob got chlorine in your water when watering.

ur plant is skinny and tiny as hell especially for 2weeks.it should be stocky by now and multiple leaves
