Need Urgent Help with Diagnosis Please

[Grow Green]

Hi Im a new grower and recently ive been having a problem with my plant for a while now and it is still occurring. The symptoms are that the leaves begin to yellow throughout different parts of the leaf and then completely yellows and wilts. I thought it was a iron, sulfur, and zinc problem. There are also burns on the plant, and I cant tell if its a plant problem or a setup problem with lights.There is also a recent upward curl on some leaves (there is a picture i upload) and the tips of most of the leaves are curled downward.I cant seem to fix the problem. Any help with a diagnosis would be appreciated. There are plenty of pictures showing individual leaves showing the symptoms.

General Setup/Grow Info:
Growing in soil
400 watt MH in a 17 sq foot area
Using Micronutrients (calmag, sweet)
Occasional Foliar Spray (spray n grow)
Fertilizer (Roots organics buddha grow 2.0-0.5-1.5)
Have an ossicilating fan

Any questions please ask
Thanks
Keep it Green

It looks like a nitrogen deficiency to me. What PPM are you feeding them at?

First check your Ph, it looks like something is getting locked out. What is your current ph? Once that's on cue, check your ppm and make sure youre not burning the plant either. Looks like ph is out of wack with a bit of heat stress.

Get a temp. gauge and put it where the light hits the canopy.
Remove all the dead leaves,
I would move the mylar higher.
Are you using the right/enough mix in your nutes?
I'm not the best but it looks hot, overwatered and under nuted.
IMHO

Stick the plant pots/plants in the shower and give them a right good flush until the water pisses out the bottom (not cold water just tepid) leave them there to dry. Remove all the dead leafes and stick them back under the lights (when the leafes have dried) and that will do until your soil is dry again and restart your feeding but dont foilar spray the leafes under the lights. See what happens then and if its still no better give them (1 feed only) of epsons mixed with your nutes.
Mix epson salts at 1 level teaspoon to 1 gallon of water and only feed one time with your nutes as to much epsons will lock out other vital nutes so go easy on the epsons as you can add it but cant take it back out the medium.
