My soil is cold (16-18) not sure exactly I don’t got no soil meter but my plants are struggling looks like micronutrient deficiency now I am going to foliar spray and humic acids what else

Nitrogen, sulfer, maybe iron and manganese... humic doesn't add nutrients its more like a catalyst. soil temp should be ok thats normal some growers boost it to get faster growth but you can still grow a good looking plant at those temps.

Sulfur & iron are the only nutrients I did not test N and MN are good N may even be slightly high I think it’s the cold (I guessed 16-18 could be 14 I doubt it though) that is preventing the uptake hence why humic acid I plan to to folilar as the uptake is in 1-3 days drench is 7-14 days

Clear plastic maybe i am worried about it becoming anaerobic nights are 6-13 day 17-26

Iron is usually only an issue if the ph is high. Sulfer can get low as the soil biology ramps up. Ammonium sulfate is the most effective form other than maybe using sulfuric acid to lower your ph. Did u test the ph of your water/ soil?

Plastic over your soil will not cause anaerobic conditions. Waterlogged soil will. Some clear plastic will warm the soil and you can remove it when the vine starts. I use an infrared transmitting film on my melons and pumpkins most of the time. It lets the soil warm up but doesn't transmit light that photosynthesis requires thus stunting weed growth. William Dam seeds and Dubois Ag sell it.
I think a little clear plastic might help but soon the weather will help out on its own.

Even if N tests high it can pose as deficient early season. Only real solution is to warm the soil. Mini hoophouses, heaters, heat cables (gutter cables or soil cables). My plants (this being the most windy, and one of the coolest springs ive ever seen) are miles ahead of any year before I started using heat cables.
Foliar can help some nutrient take up, id probably do some calcium.nitrate?
But mainly, just make sure youre watering the correct ammount, and keep spoo feeding tiny amounts of whatever the plant is missing, until the soils warm enough it can get it from there
