What is Root Rot?

Cannabis root rot is a common plant disease that affects the root system of cannabis plants, leading to stunted growth, nutrient deficiencies, and ultimately plant death if left untreated. It is caused by a variety of pathogens, including fungi and water molds, which thrive in oxygen-deprived, damp conditions. The symptoms of root rot include yellowing leaves, wilting, and slimy, discolored roots.

Signs of root rot

Brown and Slimy roots – roots that feel slimy are the best indicator of root issues.

Leaves curling/droopy – looking like an overwatered soil plant.

Musky smell – if the water reservoir has a moldy, cellar-like smell this can be an early indicator of root rot. Do a water change and reservoir change immediately

Stress signs – yellow leaves and purple buds.

Rust Spots – rust coloured spots on the leaves.

How to Fix Root Rot

  • Cut off slimy/dead roots – if the roots are barely hanging onto the plant and can be pulled off get rid of them. These roots provide food for the bacteria and should be removed.

  • Rinse roots with 1 part of 3% h2o2, 3 parts of water.

  • Perform a full water change - Perform a full water change and sterilize(diluted Clorox) your tank before putting the clean roots back in the reservoir.

  • Add 1/3 tsp ( 1.5 ml) of 35% hydrogen peroxide to 3 gal of water.

  • Add beneficial bacteria to the nutrient solution a day after adding h2o2. (hydro guard)

  • Heisenberg tea is really useful for rooting.
