Hello abhi,
First I want to say sorry for the late reply. I've been working 50+ hours a week and have only been getting one day off a week. So I just haven't had much spare time. I saw your thread but wanted to wait to answer when I had more tine, but then just forgot.

Anyhow Some of your answers diden't really give me the information I was looking for, and the pictures don't really show me everything either.

1. You told me what nutrients you were using but didn't provide a link to them. I did do a quick search for them but can't be sure if what I found is what you are using. I see a link in the picture, but you cant click on or copy and paste a link in image. Also I need to know the mixing instructions and need to know how your mixing them.

2. You said you used pH solution, but that can be anything. What I'm looking for is if your pH adjusters are designed specifically for hydroponically grown plants and not soil grown plants, pool pH adjusters, or any household products.

3. I also son't see any pictures of the roots and of inside the containers.

4. I also don't know what your water level is in the DWC container from the pictures you provided.

I did a quick search for the type of lettuce your growing because most types of lettuce are cool weather crops. Based on your day and night temps I think your air temperatures are a bit are to high. You may have a different variety but this is what I found on this site: Ilema lettuce .

I think you said you were using coco fiber to germinate the seeds, then trans planted them into the clay pellets. First question I have is why are you doing that in the first place. Second is how are you doing that? Are you transplanting the seedlings and coco into the baskets, then adding the clay balls on top. Or are you taking them out of the coco and transplanting bare roots into the clay balls.

If you try and put bare roots in the clay balls, the roots above the water line will dry out. If to much of the roots are above the water line this way, the seedlings won't be able to take up enough water to support the plant.

Lastly you said you have three 28 watt cfl's. That space your trying to grow in looks to be about 4 feet long by 2 feet wide, and you have a total of 84 watts of florescent lighting. That's not going to be enough light to cover that much space. To get good growth you'll need more like 192-216 watts of light to cover a 4 foot by 2 foot space.
