even at only 13 watts the seedling should still be bigger. they don't use that much light when young. how did u test your light to find out it was only putting out 13 watts
I dont remember the website I bought it from, but it was a legible grow light website. Now its made in China, just like most other panels. Here is a pic of what mine looks like exactly.

I have discontinued use btw as of 4 days ago, and now use a total of 66 Watts coming from two 5000k CFLs. I plan to add 2 more bulbs once I build a decent fixture. I know that for a good three weeks, I kept that panel 2 feet above the seedling, probably stretching it and damaging it. Now I have learned my lesson and have the new CFLs at 3 inches above the plant.
also, is that tin foil or mylar on your walls?
This is a Sun Chips compostable bag that I turned inside out. I know, not enough to cover the whole area. Im working on adding more necessities as i get more money.
Even at 3 days with such a low light wattage that may have not been sufficient time before watering, you shouldn't limit yourself to a schedule rather than checking if the soil is dry. People tend to say 3-4 days but then again they are using much better bulbs than a 13 watter which I have never tried myself. I personally use much more than 66 watts of CFL's also though I think that might work ?? not too sure, I still use more than that and I believe 6500k is ideal for veg growth so you may want to look into that rather than 5500k.
Your plants look over watered to me but could also be a lot of different things.
What is your PH/PPM etc..
I would guess from what I have seen it is either lack of good light/over watering but hey I am sure there are people much more experienced than myself who could shed more insight than me.
I always stick a small stick from a bottle rocket in the soil and feel for moisture. Then I double check using my index finger. I dont check the PH or PPM I dont have the meters. As far as one guy saying my stem is brown (overwatering?) but my stem and plant are lime green, turning a little greener as time progresses. Now my stem is actually green, the pictures flash distorted the image.
OTHER UPDATES: Im working on getting y-adapters and will end up ordering them. Need them for fixture to add more bulbs. Agreed 5000k bulbs might need warmer color to supplement growth. Just watered the plants today,now the stem seems flimsy and the leaves are drooping to the side.
