Farming- a bunch of catastrophies that result in a lifestyle

Hi guys!
I am using mycor this year for the first time and had a question. Back story is: three of the plants I grew last year so I know their characteristics as to growth. Soil was pro tested this year and shows above average N...so my question is:
Does mycor, through its abiity to help plants take up nutrients depelete N faster than normal? The three plants i have experience w, and several others, are showing symptoms of low N: yellow leaf margins, general paleness of new leaves. As it is my first time w mycor, i was wondering if it was the issue as to soil depletion? I cant imagine this to be the case, but dont know. Other factor, which i think is the real issue: 5 days of heavy rain. While the plants,and the surrounding 3' x 3' square have been covered, the soil underneath is saturated. No standing water, and after 7" of rain, i take this as a good sign, I am noticing some wilting of leaves as well- on all my plants, not just pumpkins, during the hottest portion of the day. Is it mycor? Is it just wet cloudy conditions for 5 days? I am going to spade the soil around the 3x3 square tomorrow in the hopes of helping it dry out- and cover patch if it rains again in the near future.
Also, how fast is all this water leaching the nutrients from the mushroom compost, and cover crop?
Sorry for length of post.

Mycho takes a while to colonize and develop. All your symptoms are unlikely to be from mycho. Mycho mostly helps your plant pull in phosphorus.

The yellow leaves could be sign of lack of sunlight. Seems likely if it is raining all the time. If you have decent organic matter and applied your nutrients in an organic fashion, like compost or manure, you shouldn't be losing too many nutrients from leaching. Back in 1993 we had terrible rains all summer. The farmers who applied chemical fertilizers had terrible crops due to leaching. The farmers who depended more on legume nitrogen and manure had good to excellent crops.

cool wet conditions the plants cant take up nitrogen.Try a foliar feed in light doses to help the plant get the nitrogen it needs. It shouldnt have much bearing on your mycorrihzae.sounds like your ground maybe saturated with rain water.
