A friend has made the most common noob mistake and over-watered. Turns out July was also the hottest month in the entire recorded history of the inter-continental U.S.!!! Sounds like pythium to me... It appears to me that his smaller plants have root rot, and I do not have personal experience correcting the rot in soil before. Has anybody had actual experience with successfully bringing a plant back in soil? Here's what I told him to do: 1. Water with lots of H2O2, Roots Excelurator, and Super Thrive. My thoughts here were to deliver a high dose of oxygen (H2O2) to O2-starved roots, kill off bad bacteria (H2O2), stimulate new root growth (RE), and help reduce stress (ST). 2. Then I told him to brew a compost tea, add Cannazyme and Roots Excelurator after brewing, and water with that. My idea here was to replace the good bacteria (with compost tea) before the bad had a chance to come back, get rid of decaying roots (Cannazyme) to prevent reoccurence, and continue stimulating root growth (RE) to help keep plant healthy. 3. Stop over-watering! I told him how to check the pots. Is this a good plan for soil? He's in Sun #4 and FF Ocean Forest.
