Leaves keep turning yellow, can't figure out why

pH is between 6.8 and 7.0, not doing anything different to the other ones, but these girls are giving me the business,I feel like they are in nitrogen lockout or something,any advice is greatly appreciated the two glue sniffer and the deluxe sugar cane all look good glue sniffer deluxe sugar cane

Try lowering your pH to a 6.5 to 6.8 range if in soil. Don't overwater to runoff unless you decide to flush but I wouldn't flush it.

I watered Sunday and brought the water down to 6.5, gave them all a gallon

When I put the blue lab in the water and turned it on to start, it was reading 8.2, last time I checked like that it was 6.8, maybe our city put some shit in there??

[Bluey]

How often are you checking pH?

[Gator]

I'll be checking everything now,I use nftg nutes and Epsom, and I usually don't have any issues,I'm going to tickle there feet and give them a little haircut in the morning

Gator, your girls look fine to me. Lower leaves are gonna die off. That is perfectly normal. If it bugs you, just pinch them off.

[Bluey]

Yes they often do but before it starts to flower is a tad early.

[Gator]

I agree with @ bluey
