try adding Cal-Mag+ to your water, looks like some calcium deficiency, maybe magnesium, too ... try 10ml/gallon at first, may be able to cut to 5ml, after a week, or two ... get a magnifying glass, and keep an eye on undersides of leaves, check for critters, too, while you're at it ... good growing :jointsmile:
the image reaper Reviewed by the image reaper on . Looking for advice on leaf condition!!! Hi Everybody, This is my 1st hydroponic indoor grow. I currently have 6 plants (3 White Widows and 3 AK47). Purchased the seeds on the internet from overseas. This week I started to notice rusty/metallic/copper colored spots with yellowing of the leaves. These are located on the fan leaves. Please click on the pics to get an enlarge view of them. I've read a few different threads, but I'm not really sure what to do at this point. Any feedback would be appreciated. Thanks for Rating: 5
