I hear what your staying but the pic's look like mild nute burn and over watering to me.. good luck

I agree on the overwatering. Check for spider mite too.

PS Make sure your drain holes aren't plugged up.

Ok should I be cleaning out where the drained water sits after I water the plants? How do you tell if you have spider mites? I only give them about a half gallon of water I think they are in 8 gallon pots thanks for the replies guys appreciate it
