What I find interesting, is the need of Ca in veg. Most of the Ca deffs Ive seen are in flower.Always looking to dump interesting info here JC!
Here's an oldie but goodie that I don't think I've linked here before. This is a pdf with plant analysis charts and graphs (with full detailed lab analysis) done on the macro and micronutrients found in three different strains of cannabis plant during veg and flower. It goes along with two videos that @farside05 posted on page 1 of his journal, where the information is explained.
The strains and analysis are from 2003, but I don't think we have modified the plant in the last 17 years to the extent that the nutrient results would vary that greatly today. Here are screenshots of the first three graphs:
What is most interesting, besides the continued need for nitrogen in flower, is how little phosphorus the plants are using compared to nitrogen and potassium.
