Zinc deficiency, how do I fix?--pics

Yes, this is a copy from the "Plant Problem" forum, but I am in desperate need for help. I have 3 weeks into grow with the following set up:

Grow room is only 2'X5'X8' tall
Auto-Pot grow system (wicking system)
Coco Noir (coconut husks) medium
Ionic "growth" formula nutes (bloom for flowering time)
Fan for building up stalk strength
Fish tank air pump to bring in fresh air
Veg stage is 24/24 lighting
Sunblaze fixture w/4 T5 24" bulbs
Ph level set to 5.5 (approx)
Nutrient mix in Ionic "Grow" is 3-1-5

As you can see, there seems to be a Zinc deficiency ( at least that's what I gleaned from the FAQ's). You will also see what happened a couple days ago (first pic) with the plant too close to the lights and burned a little. But the main problem is the yellowing and stunted growth. If this is a zinc deficiency, how can I add zinc and how much? The second plant doesn't look as bad, but is slower growing. I've never had this problem before to this degree. My first grow got a little yellow, but cleared up. Nothing has changed in the set up except that the humidity is lower (35%) because of cold weather. I have no way to add moisture at this point. HELP! please.

im not so sure its a zinc problem it could be just cause it was to close to the light put it further away from ur light and see how its doin in a week or 2. but if it is zinc i have heard that there is zinc in galvinized nails put them in the soil

With the wick type system I use, should I put the nail in the pot or put it in the water solution? And any idea how many nails I should use? Good idea btw, thanks. And I moved the lights up 5 days ago. It doesn't seem to help that particular malady

I hope there are some new readers here now, so this is just a bump to front page so you can see it and help me...PLEASE, I need help.

I put mine in the pot it is soil.
