Light burn?

[din'e medicine]

Is this caused by light burn? I have a 150w HPS on top of this, maybe 4-5 incehse away. It felt fine to my hand.

Not light burn, 150 w HPS isn't that bright. Looks like heat burn to me. You see how the top leaves are curled and discolored while the bottom ones look darker and better? Hows the ventilation of the heat from your plants?

oh man. ventilation isn't easy to come by for me

Ouch, I see. That changes things. Try fluorescent for now if ventilation is an issue.

Well, if possible, just move your light farther away... Or am I missing something?

That looks like heat stress to me.
Ventilation is key.Without it your plants will suffer and or die.

i give it fresh air everyday with a fan circulating air from the air conditioner into my closet as much as i can. I think the light was just too close. The temp with light on is 80 degrees and off is 70 degrees. Humidity is from 40-50%.

Those are great temps+humidity.
You need a more reliable form of ventilation.
You should focus more on getting the old air out then getting new air in.
