- This is from an old paper titled “Time Factor in Utilization of Mineral Nutrients of Hemp” but is still quite relevant and to my knowledge one of the best (if perhaps only) good actual scientific study on cannabis that actually accurately identifies deficiencies. Hopefully these slides will be of further use to everyone in identifying problems within your gardens.
- If anyone has any other papers or accurate information from reputable sources please post them (i know there are lots of books but the info is not easily referenced in a short summarized form as I have depicted below). The sticky guides above are great but tbo imo need more pictures and updating for better referencing.
- Unfortunately the pictures are not in color. It is available online with some searching in whole, but this is a great breakdown in jpeg slide format that one can use for reference.
- Note the similarities in K and Ca deficiencies (I see many posts with this same thing, and people labeling such deficiency in the same way) ;-D
