Cucumber plants leaves yellowing also look like fertilizer burn on leaves and crumble in hands. Still have blossoms but might not last

Thanks for the question. Without a picture it is had to understand what you are seeing. This could be a water, disease, nutrient, pest, cultural,or environmental issue. Are the leaves involved near the top, bottom, or all over. Is the "burn" on the tips of the leaves? Are the leaf veins still green or yellow like the leaf. What is your soil type and irrigation? Have you fertilized and if you have what have you used. I few pictures would be very helpful.
Looking forward to your reply,
