Thanks guys, I have lowered the light a bit. it's within 5in. of the tops. I used pebbles because there is no stores around here to order hydroponic equipment from and I didn't feel like waiting for shipping. I'm impatient.
I'll also be sure to bury them deeper, thanks for the advice.
Ok, in the picture I have uploaded there are a couple of things wrong.
1. My biggest concern is these leaves on the tallest plant. They are curling up . This happened 2 days ago when I got home all the plants the leaning over like they were leaning towards the light but I haven't moved them in...
