I now have posted pics in my diary of my young plant with yellow leaves. If you have an idea or theory on what is wrong with the plant I'd appreciate your input. Thanks!

your soil is way to cold?

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.

My manganese level is 10ppm, which is right in the middle of "Meduim" on A&L's soil test chart. My pH is 6.9. What could I add to raise my manganese level without drastically changing my pH? Or should I just not worry about it and be patient knowing that my soil will warm up and dry out in the next three weeks before my "keeper" plants are ready to be planted?

Vineman,

Your yellowing was not caused by micro deficiency. I had the same problem with my 950 Boyton earlier this year. Never figured it out why I had yellow leaves. Foliar test proved I was waaay above normal at 8% nitrogen. I also dealt with colder, wetter weather at that time.

In the end, I just pulled the plant when it showed signs of PM. Never figured out what caused its stunted, yellow growth. Could have just been a bad plant.

10ppm is fine for Manganese. 1300 pounders have been grown on half that. Leave it alone other than covering it up & if it doesn't recover have a back-up ready.

I'm having a similar problem with my plants. Their first few leaves were vibrant green, but the newer leaves seem to be somewhat pale? Could it be a fertilizer overdose? I fertilized the young plants (4 true leaves) for the first time last week with 10-15-10 and fish emulsion.

Octopus, That depends on the rate you applied. How much per gallon & hown much fluid per seedling?

Vineman, Did yours green up?

I used one gallon of the 10-15-10 fertilizer for each plant, one tablespoon/gallon as recommended by the instructions. I also fed them a tablespoon of fish emulsion diluted in a gallon of water.

I don't see what else other than overfertilization could be the cause, since I noticed it just a few days after fertilizing.

I do not believe that the color change was due to "over fertilization. Something else is going on.
