Cannabis Leaf Tissue Testing - Take Control of Your Nutrients
The chart above is an average cannabis leaf tissue lab report. It shows the ppm (mg/l) of each mineral present in the leaves and allows you to compare what's in your plants to what the lab thinks should be in them. Over time, you'll develop a feel for interpreting test results, such that you can learn more from the data. For example, you'll learn which minerals increase and decrease with pH changes in the media, or you'll learn which minerals can be high or low without causing any noticeable plant health problems.
Only in the past couple of years have we gotten access to labs who will take cannabis leaf tissue for analysis. This gives us insight into plant health like we've never had before. Now you can buy your own base nutrients and/or soil amendments and design a formula that will dial in all 13 essential minerals, which directly supports each plant in meeting its genetic potential.
If you have a formula you are using already, you can learn how to make a home-made version of it with the same quantities and ratios of the basic minerals. Along with saving tons of money, the process is very satisfying for any studious commercial grower.
