yellow okra leaves
We don't see anything concerning in your photo.
We just think it is a combination of a bit of transplant shock and roots not being fully established. These are common early problems and the plants should grow out of it.

This is a follow-up to my previous question. This week, I noticed that not only are my okra leaves yellow, they are drying up and wilting, not from a lack of water (see photo). I see similar issues of drying and wilting with my tomato plant leaves (see photo). Any suggestions?
The leaf cupping and leaf edge browning of the older okra leaves suggests environmental injury. Okra is a warm season crop that cannot withstand cold temperatures. Other possibilities are excess fertilizer salts in contact with roots or foliage. Poor soil conditions (waterlogging, large amounts of high carbon organic materials, incorrect soil pH, etc.) can also cause early establishment issues.
The spotting/flecking on tomato foliage is also probably environmental injury. If you had applied a foliar fertilizer you might be seeing a pattern of leaf spotting from the fertilizer salts.
All warm season crops set out in late April/early May have experienced symptoms associated with variable spring conditions: leaves that are yellowed, bleached, bruised, torn, punctured, spotted, and discolored. The conditions producing these symptoms include high winds, cool night temps, cloudy and rainy weather, and rapidly fluctuating air temperatures, etc. In addition, soil temps are relatively low, so root systems are slow to grow, pick up nutrients, and become established. Under such harsh conditions plants just sit and get beat up by the elements.
Hopefully, your plants will begin to pull through and get established. You may want to lightly fertilize with a complete, soluble fertilizer to promote root growth.
