Hi guys, I've just finished harvesting my second grow. My problem with it is that the plants produced a lot of tiny tiny buds and maybe 3 or 4 times less than the first grow. I suspect that the issue was at root level. The roots didn't grew that much, about 15-20 cm compared to the 80-90 cm from the first grow (I use an aeroponics system). They were all brownish/tan and kinda slimy. Please check the attached pictures and tell me what you think. Does this look like root rot?
