my progress 3 weeks into veggin

Here is my progress 3 weeks into vegging stage, let me know what you guys think about it.

I had a big problem on the 2nd one because I woke up and all the leaves were drooping and touching the ground so I had to trim them and I think it is recovering well.

Let me know what you guys think I should do now in terms of trimming or adjusting water pH.

by the way, I decided to give them 24hrs of light with constantly flowing water and they both seem to be rather happy and have been growing faster than before when I had 18hrs light and 6 15min feedings.

small for 3 weeks... what type of lights are you using?

150watt HPS. I think they are small because for two weeks the light was like 4 feet above the plants and last week I found a good way to make it about 18" and I have seen them grow more in the past week than before so I think that was because of how high the light was.

also, the roots are pretty long now and I dont know if I should fill the tank up to the old 8gallon limit because then about 4" of them will be submerged completely so I filled it up to 3 gallons and it looks like they grew longer! Does anyone think they are trying to actually be in the water? Should I just fill it up to 8 gallons again and see how they like it? I started with 10gallons and then dropped it to 8 and now i dropped it to 3. Let me know what you guys think!
