Dolomite lime.

What were you seeing that made you think cucumbers didn't like "wet feet"?

I was thinking of pulling the plastic back but if it rains the fert strip will really get drenched. I have another container with seedling just starting so I could take them up and change the ratios and try plant tone as I do have some.

It is interesting that you are using Plant tone. I had done some reading on how organics might be less than optimal compared to synthetics in containers. Obviously your pictures show that is not so!

So much to learn!
