Hi, 3rd Week into flower, first grow, 4 plants, 1 is producing smelly run off water. I notice the problem 2 days ago. I have also notice that it is consuming less water than previous. I usually feed them every other day and when I replace the water/nutes there is very little run off. However, for this plant the run off has been great, and it appears it has only been using 3/4 or 1/2 of its feed every other day. My humidity is high 66%, but I believe I have adequate airflow and temp in the days are low 70's and I have been using a heater to heat the room at night to keep around 65. PH and PPM looks good, havent measure runoff for many moons. I've read to use h202 to combat root rot? any suggestion on the main question and humidity would be great. I really can't afford a humidifier right now so any alternate solution would be great.
