Yellowing!

[jenksi85]

The plants in my green house are turning yellow. I'm not sure if its too much sun, too much watering or what. I'm new to gardening. It seems to be my parsley and my lilies are most effected, but some others aren't thriving well at all. I opted them in posting soil with a little compost.

Plant leaves may turn yellow for a number of reasons which include normal aging for foliage plants like dieffenbachia and dracaena, overwatering, cold drafts on tropical plants, lack of light, nutrient deficiency (too much calcium min the water or nitrogen deficiency) or a viral infection. Fertilizers, especially liquid chemical fertilizers, may cause yellowing of the leaves.

It looks to me like too much water. Water by touch. If you lift the pot, and it's lightweight water, if it's heavy hold off for a day or 2
