I'm 3 weeks in my first growth in DWC, and just did a nutrient change. I noticed right after the change the roots when from a creamy white color to light brown and some spots had dark brown gunk that I could rub off with my hands. Others roots are pure white as well. The temp is average of 70-77 degrees but I've been using Orca throughout the grow, ppl successfully don't have issues with roots at that temp using this product. I would say the roots may have taken color change due to dark nutrients but the dark brown clumps of gunk and white roots in some spots are having me think otherwise.
I'm curious as to why the dark brown clumps showed on the white roots, I noticed that it appeared before roots turned color but went away eventually.
Also my PPM started at 536 and is now at 500, this is the 2nd day with these conditions, leaves show no change other than slight drooping on one leaf but I this looks more like a weight issue
