It means your plants want more nitrogen. Some yellowing is normal as the nitrogen travels from older growth to the newest tips but your plants shouldnt be yellowing yet so give them some nitrogen. You an buy items high in nitrogen or you can mix used coffee grinds into the soil to hold em over until you buy nitrogen products. You can even use a bit of urine diluted very well into the water to increase the nitrogen levels. Dried blood has tons of nitrogen. I have pricked my fingers more then a few times to keep my lovelies going.
