Yes you're frying them with the light being too close if you only have Happy Frog in your pots (didn't add anything else to the soil mix did you?)

Those look prettty burned.....hope they make it for you.
Weedhound Reviewed by Weedhound on . happy frog and light distance is happy frog okay to use during germination/seedling stage. And for a seedling how far should i place a 400w MH lamp. I was told when i bought it that happyfrog has special bacteria and things that begin to grow after 2-4 weeks of water and heat. Rating: 5
