So I've only grown photos outdoor and decided to try autos. First time with tent and light. It was going great I'm my opinion. Then I noticed a brown spot couple days ago. Last couple days I've been busy but have checked on through app and cameras. Went to water em and there is obvious issue of some kind. AC Infinity 5x kit evo 8 and S16s, genetics are Dream Beans. Using recharge and full line up of growgancia nutes in 7gal pots with bio flower 365 . Thank you in advance.
