Okay. I did it. Here is the result (see pic). Now, I'm a little color blind, but it looked to me like it is somewhere between 5 and 6, closer maybe to 5. So I'll say around 5.4 which would be maybe too acidic. Do you agree with my view of the color? So I need to make less acidic I guess. Suggestions?

Also, I painted the panels of the Phototron white on the inside, so it is all white accept for some trim in there. An improvement anyway. I will get to the rest soon.

So do my plant's symptoms of the leaves curling up TOWARDS and INTO the sides -are they consisent with the diagnosis of too acid of a soil? If not... Well, it must be something else. Also, there is the other plant's health to consider...
