Calcium nitrate meal (not snack)?

sjamesNorway · June 8, 2015

My indeterminate plants are in 17 gallon containers in a greenhouse. I've used a mix which is 3 parts pine bark fines, 2 parts compost, 1 part peat and one part perlite, plus greensand, lime, and other amendments. The problem is, I think the "pine bark fines" weren't composted much, and are "stealing" nitrogen. A home test shows the nitrogen to be low, and the pH is around 6. (Phosphorous "medium", Potassium "high") I want to add calcium nitrate as a quick fix, but searching the forum hasn't yielded a good indication as to what amount to use. (I also have blood meal, but I understand this will take some time to be available to the plants.)

The plants seem to be healthy, and are growing well.

Any advice?
