GMSgrowsanswered grow question 4 years ago Brown spots in fabric planters, so many ask the same thing. There are answers to most questions if you take the time to scroll through the questions. Those planters after the plants have been in veg a while fill with roots and it makes it tough to soak the entire root system so there are dry spots in the root zone. I grew same strain always good, went to fabric planters and ran into the same problem, took me a little bit to figure it out and when I started giving them a lot more water at feed time, spots didnt show on any new growth. So 20 to 30% runoff after watering and watch the new growth. Does look a little heavy on the nutes as well. Cheers
