I have a small hydro cloner that uses a drip line to top feed my newly rooted plants five times a day. they are under 100 watts of fluorescent lights (24hrs) and were being fed a solution of 1/2 teaspoon of Shultz (10-15-10) to 2 gallons of water. They are now about 3 weeks old and while they had been doing fine, have in the past 4 or five days been developing yellowing between veins and tiny brown speckles on the leaf tips and edges. I changed the res and switched to better 3 part nutes. I mixed a half strength (according to the directions) 2 gallns and balanced the pH to 5-6 and the spots still seem to be developing as well as curling leaves. The strange thing is that only some of the plants, and even only some leaves are yellowing(etc). Checked lamps for hot spots and I'm not sure what to think. Disease? Thanks :jointsmile:
