This is my first attempt in a bubbler system, I'm gowing in 5 gallon buckets. Plants are about 2.5 weeks old from seed. 400W MH. GH 3-part nutes. Currently the system has the seedling recomended dosage of ferts. (1/4 teaspoon/gallon/nute) Also added pro-tekt. PH about 6.0 Root development looks great. This particular plant is on it's third set of fan leaves. The problem is that bottom single blade is starting fade from green to yellow. It's only slightly discolored from the new growth but I was hoping to fix any problems asap if there is indeed a problem. Should I increase the nute dosage to 1 tsp/gal for each nute or is this a matter of the PH being wrong. I'm not sure what the actual correct PH is supposed to be. From what I have seen a PH of 6 does the trick. room temp is 75 btw. Thanks in advance.
Pass it on.

Sounds like a nitrogen deficiency to me. I don't grow hydro, but I know yellowing leaves is a sign of a nitrogen deficiency. Do what you need to to correct that.
