hi there, this is my first grow and ive been getting occasional rust spots and some other problems. i took some pics of the worst looking leaves. I'm runnin DWC, in 3 gallon buckets and floraseries nutes. the plant is an autoflower and is in its 7th week. my ph is around 5.8 but i almost feel as if my ph meter is a bit wonky. The roots also started to take a slight turn brown, not sure if thats from the nutes or not but they were pearly just a couple days ago. Any help appreciated and more info can be given if it'll help diagnose it. Thanks!
