Hi everyone,

I am new here, but I have been observing the forums and this site seems like a nice community and everyone seems knowledgeable. I have searched all over the net using my google-fu and I can not determine for the life of me what's going wrong. I was growing in a seed sprouting box, ones that people use to get sapings and they for the most part grew fine, when I transplanted them I used 5.5-6.5 ph fertilizer with artificial nutrients composed of NPK 13.3-6.1-17.1. And they seemed to do fine. But now I am noticing that some of my plants are looking much greener than the other two. The leaves seems to be yellowing from the inside out. Any help would be greatly appreciated!

My set consists of a 400 watt HPS lamp with auto flower, feminzed, strains.

Attached below are two plants with problems and the last one is the one that I think is healthy.
