Common Cannabis Nutrient Deficiencies
Common Cannabis Nutrient Deficiencies
Common Cannabis Nutrient Deficiencies
-Mobile vs Immobile Nutrients
Mobile- Can be translocated from older growth to newer tissue which means the deficiency of these nutrients will first show-up in the older plant material.
Immobile- Essentially are fixed in place in the plant.
-Chelated Fertilizers
Chelated fertilizers are more stable and plant available sources of nutrients.
This improved fertilizer use efficiency
Fertilizers in this category can often be used as a foliar application in addition to being media applied which can help reduce the time a plant remains nutrient deficient.

well done
Great video! Thanks for posting!!
Thank you for a straight to the point with good visual examples video.
I had ten Cheese auto seeds that produced seven beautiful plants with great yields. One seed wouldn’t germ and I decided to grow the last two seeds. Everything went well for the first eleven weeks. The plants are big and look great but WILL NOT FLOWER! I don’t know what’s going on or what to do. It doesn’t make sense, why would the first seven plants go through their life cycle without a hitch but these two from the same batch of seeds won’t flower. Im fairly certain they’re not photos because they grew at the same rate that their sisters did. However, at this point in the grow cycle, their sisters already were flowering with healthy buds but these two don’t even have any pre-flowers . I had them on a 24-hour light cycle in soil pots outside in a greenhouse. But given that they are autos, a light/dark schedule shouldn’t make a difference in forcing them to flower right? Anyone familiar with this situation? Didn’t mean to rant, it’s just aggravating…
One off the best thanks Dude
fantastic video. thank you
I have a few plants in 3rd week of floweing and the leaves are curling up, drying and dropping off. what di i do?
Great video. Thanks for the clear presentation
Fantastic. Bookmarked for future sharing!!
Wait a sec, Urea for nitrogen deficiencies? I looked it up and Urea is from human piss. Soooooo….. I can just piss in my hemp plant and it will stop yellowing after a bit…?
I mean as dumb as it sounds, a solution is a solution and I’d rather piss in the soil than lose my plant. So… Yeah.
Awesome video. I always flush with plain water in the ph range specific to the nutrient im lacking.
Usually can fix the issue without adding additional nutes 9 times out of 10
Thank you for your video. I did not see my issue with my auto-flowering white widow. It was doing fine until these elongated "rust" colored stains started appearing on some of my leaves, which also started curling to the left or right. Any suggestions greatly appreciated.

Great job and thank-you!
I just transplanted my plants I got four plants. All the plants seem to adjust to the new soil i got 3 gallon pots with organic soil Pete moss and perlite. One of the plants is turning yellow orange color. I’m trying to keep them organic because it’s my medical plants. Any ideas what could it be? Maybe it didn’t take the transplant good.?
