Hi mkgmeash1223, welcome to the forum!! :thumbsup:

First thing first, Get a PH test kit !!!!

Feed your plants every other watering!! Tooo much of a good thing aint real good.

Your last photo looks like the leaf is burnt, did you splash some nutes on it?

A little yellowing is normal during flowering but the burnt crispy edges ain't good. I would just use water for a couple of feedings to let them use up any extra nutes in the soil.

As mentioned photos of the whole plant are a plus gives us a feel of total plant health.

GOOD LUCK!!! :hippy:
