Calcium and manganese had the problem myself, exact same thing.
"The plants above are just starting to flower and starting to yellow."This problem hasn't been fully resolved. This is my second year growing in the tropics, plants are healthy until they flower, then they go downhill.
Last year I thought it was too many inputs, so this year I kept it to a min. Recently I watered with magnesium sulphate, which may have helped a little, difficult to say.
The water comes from fish tanks, so should have plenty of N, but I doubt it is getting too much. Any help much appreciated.

That's interesting. The idea is to keep the sun off the soil. It's 35c everyday. The cardboard pretty much stays dry, I move it when I water. It's a similar idea to mulch, which isn't used in a lot of tropical countries and it may have to do with spreading mold and disease.You should absolutely get rid of the cardboard. It is a food source for bacteria and fungi.
The problem is condensation. Anything that can decompose pretty quickly is a no-no around plants. Basically you can use cardboard to grow mushrooms.That's interesting.
