Few questions

I was posting about a week & a half ago about some bad leave cupping I was having. I now have the problem under control except it left my baby N.Lights with some scars perhaps? cupping is literally 90% better the problem was very low humidity, talking 5-10% whit a 6" fan on high blowing on them 24/7 from seedling. I now use the fan to blow my hps light instead of the baby N.lights directly. I also bought a cool mist humidifier from Wal-Mart & I now blow that almost directly on them. My plants have GREATLY thanked me for the purchase because the cupping is better & they stand nice & tall now.
The Leaf in the lower right kinda now could that be wind burn? it kinda looked it to me but I am still learning & the color of the plant just seems off to me, Also Are they small for 2-3 weeks old? Sorry for the picture quality as well. Taking em under hps is kinda weird on my droid camera.

The leaf edges turning up would indicate heat stress in my experience . What's your Temps, light wattage, light distance from plant

They are only under a 150w hps, Temps are 75-83 in closet grow.About 10" from plant as well.

For a 150w the distance seems fine, but I would recommend raising the light to about 15" for a few days just to see if that will eliminate the leaf problems. Temps are great at 75 but 83 is a little hot, I noticed some heat stress when Temps got over 81. It's hard to tell with the hps light on to see other problems, (I know it's a pain to take pics with the light off too lol I'm the same way) .

It may be that the plant is still small and the heat and light power may be causing the problems, but as the plant gets bigger you can lower the light. You got it right by blowing the fan on the light and not the plant, only light breeze is needed for the actual plants just enough for the leaves to flutter. It just helps build stronger stems.

i second Alpha's response most people love the sun like plants do but not a few inches from our foreheads. Don't buy into more is better for your plant make them comfortable. Forgive my simple analogy but if you had to work hard after over eating and drinking on a baking day........... Don't try to rush the process bro.

Gotcha Redman & alpha. Thank you guys for the timely reply's. I do appreciate the advice.
