RE: Soil testing my cannabis plants

Hi @solominer, my friend, I see that you did the experiments. The first thing I must say is that I love the laboratory you have set up; it's simply amazing to see. Regarding the results, I noticed that the pH is within its range, which is excellent as it will help with nutrient absorption. As for phosphorus and potassium, very good news that they are in sufficient amounts, as these will aid in flowering, energy transfer, and water regulation. Concerning nitrogen, I see that it is in excess, and I agree with you that it is somewhat normal. However, consider a few things: First, take a look at the liquid fertilizer you are using; it could have an excess of nitrogen. If so, reduce the frequency of use or change it. Also, make sure the soil has good drainage; you can increase it by adjusting the watering, which may help to flush out some nitrogen. Another crucial aspect is to add organic matter, such as manure or animal remains. This can help balance nutrients, especially nitrogen. But, my friend, you're definitely a crack at what you do. I loved the photos and the pH meter. It's a bit different from what we use in Cuba, but the same principle. How beautiful everything is, how beautiful science is. Well, friend, you know you can count on me for anything. Let me know if you need anything.
I was pretty happy with the setup and I think it gave me some solid results.
Ah true, I need to see if I can find a lower nitrogen for my flowering plants. Normally I feed them a nitrogen rich fertilizer when they are growing their leaves. And then switch to a lower nitrogen level for their flowering.
As for watering I use a moisture meter and they get around a gallon of water just about every day at this point in their grow.
Glad you liked the photos and my equipment. Will do more posts as I test my outdoor soil and my pond alkalinity.
Perfect friend, I look forward to the publications with the other experiments, you know that I love chemistry and your publications. Check out the fertilizer and tell me how it went. Thank you for sharing that valuable information with me, I am happy about that.
