Yeah, I'd say do 1 6500k bulb per seedling once they're at least 3 inches with their second set of leaves(not the round starter leafs), and then add a 2700k at the end just to mix spectrums. Once they get to be about 5-6 inches tall, or if they look like they need more light, I'd do 1.5 6500k bulbs per plant, and then add another 2700k cfl.
Also, if the effective wattage isn't above 100, they're not really worth it. Now i'm assuming you know the difference between CFL wattage and effective wattage, because those 26w cfl's you're using are probably all 100w equivolents, that means you were initially hitting your seedlings with 1,200 watts of light.
And seedlings in their first stages only really need indirect light to get started. You were putting them on the surface of the sun there for a little bit
Now i know what you're thinking "What if I have 12 seedlings?" The rules can bend, and they generally say 1 bulb per plant, however you gotta remember, the light will be reflected throughout the box, so its not too big of a deal. But judging from the pictures if you onyl had 5 seedlings at first, I'd do 3 6500k cfls at 100w effective each, and 1 2700k cfl at 100w effective. Until they're big enough to handle more light. A good rule of thumb when watering with soil, which yeah I understand can make you nervous at first, but a great rule of thumb when they first get to solo-cup size, is to completely drench the soil first. You do this by getting 1 cup of water, and pouring in 1/5th at a time until it comes through the bottom. After that, leave'em alone the rest of the day, and continue watering as normal. Generally seedlings need a shotglass of water twice a day. Once at the beginning of their photo period, and once at the end of their photo period(assuming you give them time off). You certainally don't have to water until it drains out the bottom everytime, you'll over-water them. Also, becareful over-watering peat moss pellets. To water the peatmoss pellets, I usually just take it with the seedling in it, and dunk it into a cup of water for 5 seconds. then squeeze it gently and let 10 drops or so roll out the bottoms/sides, and its hydrated plenty.
A novice mistake would be to put peat-moss pellets under those lights, it'll cook the moisture right out of em and they'll fall over dead within a day. So once they pop out at least an inch or two, put'em in a solocup size of soil. Also, after you get them plenty hydrated and go back to normal feeding, you don't have to put the shotglass down into it, don't think you've got to like stick a screw driver and ply some room so the water can get down to the bottom. As long as the water hits the top roots near the stalk of the plant, it'll transfer that moisture down to the lower roots.
Hope this helps.
