I took the advice from the three comments on the previous blog entry. I mixed a new nutrient solution with warm, close to hot, water and added two gallons to our can. After looking up the ideal pH of baby mesclun, which is what we are growing, I found it should be between 6.2 and 6.8. After mixing the solution and checking the pH, we found it to be around 6.5 which is good. However, we added a tiny bit of pH Down to the solution to making it a little lower. Our one plant I mentioned before that seemed to be getting worse looks the same with no progression. From another comment, it seems we are not the only group with this issue. With advice from Dr. Brusic, I added MESCLUN to see if this grows (better or faster). Something needs to happen soon, or I will again have to rethink some things.
*NOTE: PICTURES WILL BE COMING SOON! our plants have not made much progress, so therefore we will take pictures when we see more of a difference hopefully.*
I tried to comment on your most recent post, but i am glad to see your system is finally working out for you! It is a very awesome idea and in theory seems like it should be low maintenance with the floating platform for the plants. I look forward to seeing more updates!
looks like a cool easy design if you can get your issues straightened out and plants to grow.

During our experiments Phil and I have had problems with Ph also, apparently it is an everlasting battle. Today on November 4th we finally got the pH AT 7.0 and hopefully it sustains.

Hopefully that works out for you.
