Yellow leaves on the of the plant

P and K deficiencies beginning.

m0use say what ? I am THE chart xD all u have to do is to lisen to me xD

This chart can help a bit. https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg good note about PH check but soil manages its own PH well unless you been messing with amendments and mixing in a bunch of stuff.

N deficiency that starts from middle of the plant xD Yeah xD

Micro nutes deficiency outdoors in soil ??? Would say its almost impossible. Potassium looks like more possible issue ...

It's be rare to have a trace element issue outside.. and "organic" is a marketing team with no specific causality due to such a designation. Also, did you know "CO2" is an inorganic element? There are numerous inorganic molecules necessary for life. It has nothing to do with life / non life or natural/unnatural. It's a misappropriated science term that even in chemistry does not carry much weight.. it's more of a loose distinction that has had to be re-defined at least one time because the initial definition was not realistic. anyway, looks like a K-deficiency or something locking out K. Looks like yo may have something else going on lower on the plant, too? If it progresses differently it's a 2nd symptom - either something else deficient or part of same lockout. Can't see enough to give a good guess. 'organic' products often have more inconsistency from batch-to-batch, not always but is something to consider when using such products. You can send in a soil sample to a company like JR Peters and they will provide an adjusted formula for your context, if you want to skip the trial and error of figuring it out. It can inform about pH issues or whether your soil in backyard is over-abundant or lacking in certain nutrition compared to average.. and suggest a ratio of nutes to provide etc... can send in a water sample to adjust a formula to your tap water contents too. or, be systematic and try one thing at a time each grow until you have a positive response, otherwise throwing multiple solutions at it will only create more confusion as to what actually worked. I don't think theplant looks overly lush, so i'd look into a soil slurry to test pH and if that looks okay (be forgiving as soil slurries are imprecise as is) try bumping ratio of K in any fertilizer you provide while maintaining other stuff. if that yellowing at bottom is tip-in progression and bottom-up on plant, i'd add N-deficiency to list, but could easily be caused by too-acidict soil or some other nutrient at high levels impeding it's availability -- again, can't see it well in picture.. but N-def is the easiest thing to diagnose based on the description i gave.

P,K deficiency up the dosage of ur bloom fert
