Gorilla Cookies auto showing brown patches. Can anyone tell what this is?

xadenstarted grow question 6 days ago

Growing in soil (super soil gaia green) with dry amendments. @ day 44 of flower. started noticing some brown spots on lower leaves, then on some upper fans and now on quite a few sugar leaves near canopy level. Does anyone have an idea at first glance what this might be?

Looks like early potassium deficiency, common around mid-late flower. Spots spreading from lowers to uppers and sugar leaves fits that pattern. Super soil can run low on K by day 40+. Consider a light top-dress or K-focused supplement if fading accelerates.
