Yellow

[mytur88]

I'm currently using foliage spray for calcium and magnesium, im hoping its that i missed the bottom of this plant. the other little bean leaf is green. 2/4 of my plants are doing this and the other 2 are fine. Any suggestions?

They are going to turn yellow,they are there for energy for when the plant is a seedling and the first leaf to die off

Its looking good and like Toddosh said its just a seed leaf, The seed stores food for two weeks then its time to feed did you have any nutrients to feed later
