I have a couple of plants that I have been experimenting with inside a hot house. They have been in the hot house (planted in the ground) for about two weeks and are kind of a sickly yellow color instead of bright green. The plastic covering the hot house is kind of opaque (instead of perfectly clear). I'm sure that my soil is fine (I can guarantee you that it is not a nitrogen problem) and am starting to believe that the lack of true sunlight is the problem. What do you think?

Too much moisture in the soil and thus a lack of Oxygen?

I had the same problem happen to my young plants last
year, have you been applying any ferts to the plants?

myself I would stay away from any kind of ferts till the plants look like they need any

it could be lack of oxygen or maybe an overdose of ferts

I haven't applied any fertilizers...just the manure that was put on the patch last fall. Could it be an iron deficiency?

Vineman, Did you have a soil test done before and after the additives to the patch?

Yes, I had a soil test done about a month ago. Everything is high to very high.

I do not believe we're dealing with a soil nutrient deficiency at all. Rather there is still a tissue nutrient deficiency. The question we need answered is simpler than this statement might suggest. The answer requires another question:

What is the soil temperature? Stick a thermometer in the ground for 5 minutes & post the results.

Vineman, I am in Napa, about 40 miles from you. Does Santa Rosa have the heavy adobe soil like Napa ? I have a water retention problem here in spring until the weather warms up and the soil dries. Some of my tomatoes look a little yellow right now (this is not uncommon in April in my soil)......however they usually pull out of it in May when our rainy season is over and the weather warms up and our soil drains better.

I'll get a picture up tomorrow in my diary. Yes, we do have heavy, clay soil...but mine is heavily ammended. However, if you go down 8 inches or so the soil is adobe clay. It is wet when you dig down six or eight inches.

59°F soil that is water logged is absolutely Nitrogen deficient. Applying Nitrogen in this situation would likely harm the plant. So we need to wait for warmer drier conditions before this plant perks back up. Soil heating cables & cloches are used to better regulate these conditions & perhaps should have been employed.
