First problem, just need second opinion.

I believe this to be a mag deficiency but if someone could give me their thoughts please.

i have the same problem with mine

ya pics arent good...but it looks nute burnt. clearer pics, and we can say for sure.

no its third week veg. the leaves are curling up, and I have a table of potential problems and nute burn says the leaves curl under not up.

also I am only at like 50% what it says on the label. using botanicare pure grow

A good description is they are dry and crispy along the leaf edges, yellowing on older leaves with light brown spots forming yet still with green veins.

ya i havent ever had one certain way a leaf folds after nute burn...but in any case if you think it is mag deficient, go buy some cal mag. folier feed... give it a week, and if it still isnt improving, then you know it was nute burn. at any rate it is always good to flush at bare minimum twice during the entire grow. once before your time switch and bloom nutes, and again 2 weeks before harvest.

aaaahhhh shit. just noticed the pic on the far right...the reason you have your lights above the plant, or on the side is because the tops of fan leaves are where the light energy is consumed, and the bottom of a leaf is how a plant breathes. get rid of that windsheild reflector out from under that girl or shes gunna twist like hell.
