Diagnosis Buddy

Cannabis Plant Problem Diagnosis

Something wrong with your cannabis plant? Answer a few quick questions and get a diagnosis — yellow leaves, spots, pests, bud rot — plus the exact fix. Free, no signup.

Something is off with your plant and you cannot name it. That is most of growing, early on. Diagnosis Buddy asks you a few plain questions — what you are seeing, where, on which leaves — and lands on the most likely cause, the fix to do now, and a link to the full guide if you want the why. It covers 37 of the usual culprits: yellowing and spots on the leaves, airy or foxtailing buds, soil and root trouble, odd growth, the room itself, and bugs or mould. No login, no jargon to go and Google. It will not replace your own eyes, but it tells you where to point them.

Questions

Is Diagnosis Buddy free, and do I need an account?

Free, and no account. You answer the questions in your browser and the verdict comes back on the same page — nothing saved, nothing to sign up for. Come back whenever a new problem shows up; it is built to be used mid-grow, phone in one hand, plant in the other.

How does it work out what is wrong?

It narrows things down the way a grower would: what you are seeing, where on the plant, old growth or new, and what the room is doing. From your answers it picks the most likely of 37 causes, gives you the fix to try first, and links the full guide so you can check it against your own plant.

What can it diagnose?

The common ones that trip most grows: leaves yellowing, spotting or clawing; buds that come airy or throw foxtails; soil and root trouble; stunted or stretchy growth; heat, cold or humidity in the room; and pests or mould. Thirty-seven verdicts in all, each with a fix and a guide behind it.

Is a verdict a guarantee?

No — it is the most likely cause from what you told it, not a lab test, and plants rarely read the manual. Take it as a strong starting point: do the fix, watch how she responds over a few days, and run it again if the picture changes. Your own eyes are still the final call.
