Help I am only a simple grower

[harris7]

So my leafs have some yellowing and it is moving up from the lower leafs, See pics.

Iâ??m thinking it is a mobile nutrient problem as the growth tip seems health.

Nitrogen Def?

They are under 400Watt MH and the temp is always under 84 usually at 81 F

I have been feeding but not for the last few days.

Thanks

Ps-the pics are listed from lowest leaf to highest
