Sorry for the late response, I’m using all rock wool medium Hugo with rock wool mini cubes. ph 5.8-6.2 ppm 1100-1200. Feeding sensi bloom. b52, cal mag, bloom boosters. Running a water recirculating system in bucket. the plants are under vividgro led 600w about 20-24 inch away from tops. It’s seems the discoloring is bottom and top. not every single leaves are like that.
mis read my ppm is 1100-1200 but I don’t have run off that drips off the bottom it’s just whatever goes back to the reservoir and my blue lab guardian tells me it’s still at those levels. It’s ebb n flow bucket system.
It seems the new leaves are coming out ok now. The light distance from the top is about 20inch away. I up the cal mag and ph at 6.1-6-2. Seems to work, I’m at beginning of week 4 now. Thanks mrgrowit.
Potential iron lockout? Can you give us more information. What medium? What is the pH and PPM of the runoff? What grow light are you using and how far away is it from the top of the plants?
