So I am have been trying to figure out what happened to the three plants I put out in hoop houses last week. All developed thin soft mushy wilting discolored leaves, with cot leaves looking the worst. Doing a little research, apparently cold damp conditions and lack of sunlight are conditions for damping disease. I did not help the cause any by keeping the hoop houses closed tight in attempt to keep them warm. I also noticed a small amount of white fuzz on the ground under one, now realize it was probably fungal. I am hoping my 1985 will recover. It had heating cables under it and looks the least sick of the three. Any way, thought I would post as a heads up. Also appreciate any suggestions on possible treatments for the 1985. Picture can be seen in my diary.

I checked your diary and It shows you put down 200 pounds of 0-0-50. Did you have a soil test done first before you put that much 0-0-50 down and tilled in? Several years ago I needed to raise my Potassium, Joe Jutras told me not to put more then eight pounds per 1,000 square feet.

Potassium

Potassium levels are naturally adequate to high in most Colorado soils. With annual applications of compost or manure, potassium levels will likely be adequate. Deficiencies occasionally occur in new gardens low in organic matter and in sandy soils low in organic matter. A soil test is the best method to determine the need for potassium.

Excessive potash fertilizer can increase soil salt content.

Where potash levels are believed to be low, the standard application rate without a soil test is ¼ to ½ pound potassium chloride (0-0-60) or potassium sulfate (0-0-50) per 100 square feet.

Movement of potassium in soils is dependent on soil texture. As the clay content increases, movement decreases. For most soils, it is important that applied potash be tilled into the root zone. In sandy soils, potassium could leach down past the root zone.

If you noticed the fungi, get some air circulation or open the green houses. It'll help dry the soil and get rid of the stagnant air. Good luck

Looks like a chemical or sunburn. Growing part of plant looks fine in the picture you posted.

Just looks like sun scald to me.get some air in there and dont over water.
Let the roots go searching for some water.this way you should get a deep root system.

Looks like outgassing burn to me also.

Chemicals volitalize and become trapped in the hoop. Sometimes the droplets of water on the plastic magnify the sun creating burn.

Got the hoops open and sun is shining. I didn't think sunburn cause it's been nothing but cloudy. But seeing how people can get sun burn on cloudy days I suppose plants can too. Pulled one of the three cause had back up that looked great. 1985 looks pretty good except for the cots. Fungi seemed likely based on conditions. Humidity was over 90%Certainly were lots of water droplets on plastic. Appreciate the help, consensus seems to say sun burn, and I will make be more cautious.
As far as the potassium goes, yes I had soil test...
..% Base saturation Ca 72.9%, Mg 25.9%, K 1.2%.
K ppm = 116. I have 5,926 sf patch.

Appreciate all the help.

I agree with the sun scald/sunburn. You might ask how I know this lol. I'm willing to bet they will be just fine.
