rqs watermelon auto 1st time grow

Hi everyone, I have had problems with plant 1 since the start of the week. First, I was thinking a cal-mag deficiency but actually detected a garbage smell located on one side of the bottom of the jar. I add a start of root mold 😢, just during the first week of flowering. After researching how to fix this and asking some grower friends, I gave her a bath with 10% bleach for 15 min (after loading the perlite with fresh water). Clean everything and disinfect (of course, since I detected the smell and brown/dark roots, I removed it from the communicating water system and quarantined it). After a cleanse of the roots with fresh water, I add mycotrex, bacteria (tarantula) and voodoo juice to set up the whole organic base inside the pot. 24 hours later, the smells have disappeared and my little girl is better, I will carefully monitor the rooting and growth. For the next 24 hours, I will start feeding again to give the good mold time to develop before reintroducing phosphorus which can quickly kill the beneficial fungus. This security will surely affect the bud, but I choose to save a small harvest instead of losing everything...
