I don't think you will be able to measure your calcium levels without lab testing. We used a custom fertilizer mix that was put together based on our water sample. It involved mixing specific amounts of each component Nitrogen, calcium etc. You want your solution to be slightly acidic so that looks good there, but that can also have an effect on uptake of nutrients. You might research mixing your own formula that way you won't be chasing your tail with the unknown formulation of the miracle grow fertilizer. Hope that helps

Heh, it never clicked in my head up to this moment, but I can easily get the data on my water composition (a friend has a brewery and we share the water supply) and I also have some of my brewing supplies for treating the water to get it to the right composition for beer so I'll just have to have a play with the numbers.
This was the first year I grew hydroponically and the plan was to mix my own, but then I needed something quickly and the miracle gro seemed to work so I just stuck with it. For the next season I will mix it myself.
Thank you!
Oh, I've just seen some of your farmer's market produce posts. Your stuff looks great!
Have a look at growing some lemon cucumbers and cucamelons, they really draw people's attention. I have some and they grow really well in my greenhouse. The cucamelon plants put hundreds of those little cucs.
wow...sounds complex and dounting for me. I aspire to one day have my own greenshouse and probably do hydroponic. But the "science" part of this is rather scary...not sure how I would get that right.
