It looks like the plant isn't making a full pH swing. Over fertilization will show in new growth before old stuff so if its isolated to the bottom of the plant its pretty safe to sat pH.
what are you feeding it?
I bet it would love some plain water for awhile. That pot in the background, whats that white stuff on top the soil ? The leaves on that one look like they're N toxic.
Yes definitely nutrient issues. What has the feeding frequency been?
Try one feed 2 waters, and be sure you let about 15% of the watering/feeding to run out and away from the drainage of the container.feeding according to the online maxibloom schedule posted by general hydroponics. Every other water has food in it.

Don't change when you water/feed as far as how many times/week. Just change the number of feeding to feed/water/water/feed/etc. if you pay attention to how much water the plant uses you shouldn't run into overwatering problems. If the soil is dry to the touch about a nuckle or two below the soil surface then that's a pretty good way to tell if it's time to give moisture.even if my medium is 100% soil? people warn about overwatering and i dont want more gnat issues
