Cannabis tissue nutrient analysis - Cannabis Botany and Advanced Growing Science - International Cannagraphic Magazine Forums

There's a lot of interesting information out there about cannabis tissue nutrient analysis. I have two questions
1. Are you supposed to use this information to know what to feed?
2. I noticed how low Phosphorus is during Veg and Bloom, but how high Nitrogen, Potassium, and other minerals are during the same period !

My take on this topic is that tissue analysises were most likely made from a couple of leaves from 1 or more plants.

- what about the stalks, flowers, roots
- leaves from different parts of the plant will have different nute content
- nute content also depends on growth stage, feed regime, the time it was last fed etc.
-just because the plant foliage contains nutrients in a given ratio, it doesn't mean we should supply the same ratio in the nute solution, different amounts might be beneficial for shorter internodes, more THC, might aid other nutrients uptake etc.

How about comparing the results of tissue analysises made on tomatoes and the nute profiles used with them.
