The stages of my corn growing

#1 here are the seedlings first sprouting

#2 here they are again but starting to gain some height and the first true leaves

#3 after a week in the containers this how they have sprouted

sorry for the sideways image, maybe someone here can help/tell me how to rotate the images for I could not get it to fit right. the picture itself was not taken this way sorry.

#4 ok, so here is the most current photos of "my corn growing"

picture taken today 05/29/2018


I noticed some of the leaves turning brown, I think either I missed a day watering or the pots are to small and the roots are getting bound. If anyone can tell me if the containers are too small or should I start to add plant food/fertilizers ? all comments are welcome. thanks guys …..and I hope you enjoy my corn growing experience.
