Raised beds, gypsum dug into clay-based soil, Hortico Garden soil and 75 mm of dried cow manure is growing medium in the beds. Regular watering, soil is moist down to 300 mm. Shade cloth erected 1500 mm above garden for shade/heat protection (45 degrees here today!!!). Mineral deficiency?
Overall pale leaves is a classic sign of nitrogen deficiency; it could also be a pH problem which is making it hard for the plants to access minerals. https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/nitrogen-plant-fertilizer.htm
You can also call the nearest botanical garden for information about contacting a master gardener group, who will help you with analysis and treatment.
My spinach develops some slightly large swellings and in the end dries up. What may be the cause?
I'm not sure the issue by just this description of 'large swellings', but my best guess would be some sort of insect damage.
The dried edges could be from the same issue, or possibly a watering issue.
Neem Oil is a good treatment as it acts as a fungicide and pesticide if you want to attempt to treat the spinach.
Spinach does prefer to grow in cooler conditions.

Trying to grow Amazon spinach and this has happened. Not sure if disease or bug, or what to do. Any help?
I think this is White Rust, a very severe case.
Remove and destroy the plants.
Practice crop rotation and plant in different location in the next year.
I have planted English spinach in planter boxes in my back veranda. They get morning sun and have produced fantastic leaves for the first couple cuttings. Now some of the plants are starting to grow inward to the stem, looking like shell pasta. Half the plants are now growing this way. I also feed the plants once a week with NPK 5 in one liquid fertilizer.
Leaf curl is likely due to Aphids. You can use a blast of water to wash the leaves.
Insecticidal soap can be used to control Aphids.

I know the greens of beets are edible, but does that include the buds and flowers that are a result of bolting? I have India Beet Spinach and want to be sure it's safe, as I am 10 weeks pregnant. Thank you!
As I am only allowed to dispense gardening knowledge and not medical advice, I am going to ask that you refer this question to your physician.
One day our spinach was growing just fine and the next day they all looked like something had been sprayed on them, but not. The lettuce next to them was fine. The spinach in separate bed was the same way. What's up?
This sounds like dampening off fungus.
Dampening off is a fungus that lives in the soil, particularly in humid weather.
Do not plant Spinach in cold, damp soil. Soil should be well draining.
My spinach went crazy with all the rain we've had. I've aerated the ground and now my spinach leaves are pointed. Not the round oval they used to be. What happened? Should I be worried? Can we still eat it? Sharla
Spinach that is grown under stress becomes pointed.
This is a great way to tell the health of your plants.
It is perfectly fine to eat, but may not have the best flavor as a happy growing crop of Spinach.
