Slight yellowing of leaves what does it mean???

Ok perhaps I am looking at these plants too closely. However today I notice a little yellowing to the lower leaves of the plants:neutral:. They are mostly green and appear healthy, but want to remedy the situation if this is a bad sign. I can only think that this may be an overdosing of nutes? I used a full strength dose of shultz 10-15-10 food, mixed 7 drops to a quart of water (I always let the water stand for a couple days before adding liquid nutes at the time of watering). I am guilty of using full nutes on these plants at 4 weeks:roll:, then again four days later as the soil got nice and dry. For the third watering I got a little scared and just used plain water to flush. I am planning on alternating now back and forth between plain water, and water with nutes. I might want to lower the dosage too? Perhaps if a full quart dosage is 7 drops, I could go 4 drops to a quart, and gradually increase weekly?

You can find commercial phosphate or nutes high in phosphate at most hydro stores and gardening stores.
I'm sure there is a natural organic way to correct this, but unfortunately I don't know of one.
I think there's certain manures high in phosphate but I don't remember which.
Maybe a more expeirenced soul out there knows and will respond.
