Whats is wrong with my plant? Coco

It's roughly 2-3 weeks old from seed in coco. Ph water/nutes to 5.8 gave it a little bit of cal/mag and olivias clone solution a week ago. Under a 250w hps air cooled about 4-5" away. I can touch the tube and not feel heat at all so I dont think it can be heat. Anyone know what the problem is? Thanks

you need to feed it

The light does sound a little close. Have you fed it any real grow nutes?
I've never used clone nutes!
All most looks burnt maybe the light or the nutes?
I'm voting nutes

I'm willing to bet he didn't.. Calmag only has minute amounts of npk to make the calmag work, not enough to support lush growth

Nope no real nutes yet. I only gave it olivias cloning solution because I was waiting for my nutes... I have them now so I should feed them or can this be from too much calmag?

I go by ppm's~seedlings that size 200 ppm's.
Here a pic of my I gave it 1/2 tsp of Grow Big
per gallon and it was right about 200 ppm's I
think this one in sunshine mix 4
