Fundamental FAQ: Diagnosing Yellow Leaves in Living Soil
I’m continuing my Fundamental FAQ series for 2026, designed to help growers build a strong foundation and make informed decisions with confidence.
In this episode, I tackle one of the most common challenges in living organic soil: yellowing leaves. Rather than immediately assuming a nutrient deficiency, I walk through a systematic approach to identify the root cause of leaf issues, from environment and watering to soil, pests, and reset protocols.
This video breaks down why deficiency charts can be misleading, how environment and watering play a critical role, and why living soil provides a margin for error that hydro systems do not. I go step-by-step through a yellow leaf checklist, offering practical advice for new and experienced growers alike, helping you understand the “why” behind what you see in your garden.
By the end, you’ll have a clear framework to confidently diagnose yellow leaves, prevent recurring issues, and nurture healthier plants without guesswork.
