First Mephisto attempt

Started these girls last Tuesday. I had a problem when I tried germinating my auto Grapey Walters from Mephisto. I believe that I had them get too dry on the paper towel before I tried planting the seedlings. But now my forum stompers have started and only one of them is looking like it's a little slower than the others(#4). I started this grow using coco and fox farm's happy frog all purpose(4-3-4) organic amendment, this way I will only need to feed in about 4 weeks once the plants have consumed the nutrients in the coco. Two of them seem to be showing some kind of yellowing on the leaves and I don't know yet if it's a light or nutrient deficiency. Later in this grow I will also be using a bloom fertilizer and bat guano, all from happy frog to finish their flowering stage. This is all for this week I will come back next week with more pics and updates on these 4 babies.
