Those plants all have severe yellowing...not normal yellowing...

And pic #5...that has something seriously wrong with it.

I wish I could help but I have never really studied outdoor grows in detail enuff to diagnose this one.

You need some help on these.....

FOr the future,., never do the same thing to ALL the plants.

Do at least a half and a half to help minimize widespread problems and to identify the good things.

If I were you, I would throw away the Miracle Grow.

Add some fish emulsion...5-1-1.

But thats what I would do and I speak for me alone.

Good Luck.
