Is the heater blowing right at your plants? Cause if it isn't and th room isn't 90 degrees, then it's not the heater.
What kind of soil are you useing? what kind of nutrients are you using? What's the temperature and humidity of your growroom?
 
Temp is 73 right now but varies from 65 to 79F. In garage so hard to control.
Used MG moisture control and didn't add any extra nuts.
 
Get rid of the heater. Burns more watts than a light, could be causing your problem and isn't helping your plants to grow. If it's too cold, use a bigger light, you're in veg!

Toasty is the word I'd use. I'm thinking that soil may be too hot.

Just out of pure curiosity here...what makes you think N deficiency? The plant is dark green and the leaf margins are burnt to a crisp. This plant is either overferted or he's got that heater blowing on them. My first guess is actually that the soil is too hot and it's overferting the plants, second is the heater thing. Nothing here looks like underfert to me, maybe I'm missing something?
 
Without heat I'm fucked! There in my detached gargage and it's getting cold at night. I had a slight frost on my car yesterday.
I have no room right now for a ballast set up. CFL's and T8's is what I have to work with.

I think it got a bit hotter than that, you singed the leaves on one side, point it away from the plant.

Your right one day i saw it at 84F, who knows how much it varies at night when I'm not checking them.
Yesterday I turned the heater away from the plants to reduce the direct heat...this morning I checked on them and it was down to 49F!!!
If there females I'm probably stressing them into hermies!!!!
