Northern Lights x Big Bud auto

Pots were still heavy when i checked them on wednesday 16.09. Last watering was on friday 11.09 so i unhooked the wires and took out the plants from the pots. The soil was proper moist from bottom and up to 5 cm from the top. When checking for moisture with my fingers prior i noticed the soil was slimy. The soil had the same slimyness out of the pot as well.the roots on the bottom looked fine though. I also noticed small White worms creeping around. I decided to flush the plants again in horror. Ill add more lecaballs to the soil next time as people have told me it could be becaue of bad drenation. Also removed dead leaves for better light penetration.
