What are they in what are you feeding them what size light.
Yellow Leaves, Iron Chlorosis
Yellow leaves and green veins are often the result of a common problem called iron chlorosis. This is the result of either an iron deficiency or iron unavailable for plant uptake. Iron plays an important role in producing chlorophyll, a green pigment involved in the absorption of light needed for plant growth. A deficiency in iron results in a reduction in chlorophyll producing a yellowing of the leaves. This is an early sign of iron chlorosis. The leaf veins remain green while the area between the veins turns yellow-green to yellow. In severe cases, the leaf color may change from yellow to white and finally brown. Iron chlorosis is most often caused by iron not being readily available for plant uptake. High soil pH makes it unavailable for plant uptake. In alkaline soils with a pH above 7.0, most plants are not able to take up iron. Once iron chlorosis is confirmed, several methods may be used to provide iron to affected plants. Here are several ways to treat for iron chlorosis.

Here are several ways to treat for iron chlorosis.
- Foliar application - If a rapid response is needed to correct a chlorotic condition, a foliar spray with iron sulfate or iron chelate solution may be applied when the tree is in full leaf. This treatment is not very effective however. It is only temporary. New growth that emerges will be chlorotic.
- Soil treatment - Since iron chlorosis is often the result of high pH or alkaline soils, lowering the pH would be the most reasonable solution to prevent chlorosis. It is difficult however to lower soil pH at depths of 18 to 24 inches.

...what kind of soil, and how long ago was your last transplant?

...rapid release dolomite lime, 1 tbls per gallon of soil as a top dressing and water it in as normal.

...since you've had your plants in the same pot since seed and you've been following up with the Trio, I doubt there's a lack of fertilizer in your soil....do you pH your water?

I would up the N some for the next week or so.

....Lowes, Home Depot. The Rapid release dolomite lime will fight to keep your soil's pH @ 7, or neutral. You'll also provide your soil/plants with trace elements such as cal./mag. with it.

....damn. Well, that might be your problem. Try to get your pH in check, all the elements in your soil will not be available to your roots until you get your soil slightly acidic.

....that's not good. You need to be around 6.0-6.5 in soil.

...I've heard of several different ways to lower your pH with house hold products...but, I would go to walmart, or a petstore that sells fishtanks, and ask for some pH down....and a liquid ph test kit to read your pH. Letting your water set out over night is a good idea, you will dechlorinize it by doing this, but...it will not lower your pH....the water companies raise the pH of water to prevent pipe corrosion.
