Hello @ExperienceTrueLevel
Hard to say without more details of medium, nutes, watering etc

Nicely done photograph. Like Roy mentions a bit more info on your grow will help pinpoint how to take care of the problem. Details like whether it is being grown in a hydroponic set-up, a soil-less or a soil type of grow medium. Plus the type of fertilizer and how often it gets fertilized, etc.

Once we know that some will start making suggestions on what it could be and they will need you to pinpoint a few things but it does lead to a quicker tips on what to try out to fix the problem.

Thanks for the replies! Its outdoor, really only fish emulsion, gaia green 444, worm castings and compost i make at home. Been fertilizing about once a week and soil is just a micronized promix in 100L sqaure bin, i water when she looks like she needs it maybe 2x a week because the soil is still super wet down in the roots when i put in the tester
