2nd week of flower yellow upper leaves (Pics)

I dont know how much of a problem this is an I was hoping for some advice.. It seems to be happening to the ones directly under the light the most.. thx for any help

1000W HPS Air Cooled Hood
Temps 70-80
Humidity 40-50
Nutes Canna Terra
pH. 6-6.5
Filtered Water

Pics are kinda hard to see cuz the HPS throws the color off a little bit but I think u can see what im talking about

I don't see any yellow in the pics. This is early in flower to start running out of nitrogen, though that is what it usually is.

LOL its a really light yellow but noticeable.. I might just be overreacting this is my first grow

next time you take pics, put sungalsses over the camera lense, that will get rid of the lines...but maybe add some veg. nutes to your feed and help get some N in there?

Alrite coo ill try the sunglasses trick next time.. thx

sunglasses lol nice... never thought of that. Or you could always shut your hps light off to take pics, works great ; )

I would also agree to up the N content or she's just gonna keep yellowing till eventually all your N has been sucked outta the fan leaves and budding will be slowed

It looks like there starting to correct themselves.. I didnt do much I guess they were just getting used to the new light schedule..
