With high roller and you on this. pH fo sho. As for reading your pH, are you able to calibrate this specific meter? If so, a 7.0pH calibration fluid can be used to put that bugger back in check. Two brands of this fluid are blue lab and Growtek (blue lab is expensive though. Go with a cheaper version).
If you can't calibrate this meter and/or don't trust it, I highly suggest a manual pH test kit. General hydroponics is a decently priced option and lasts for a long time. I actually do a test with my meter (calibrated) AND a manual test to prove the results I'm reading. If something's off with the meter, the manual test will tell you so and I'd personally take the manual reading over a fallible electronic anyday👍👍
Good luck and don't give up! I trust there is time to bring them all back to health (even the little guy). Cheers👍😉

Progressive yellowing on older fan leaves ~F14-F35Hi, past two weeks or so I've been noticing progressive chlorosis and eventually some necrosis starting from the edges of the leaves and working inwards.
Photos of this can be found in Week 18 Flower denoted by "For grow question #x 12/1"

brown spots sugar leavesI've asked this before, but the issue still seems to be there though it's very minor. Some of my more developed buds sugar leaves are showing brown markings. Last watering I flushed her but the markings seem to be spreading still, although very slowly. What am I dealing with?

Just to confirm, this looks like nute burn, doesn't it?Burnt edges, tips curled up, canoeing. I've been having trouble balancing airflow and heat in such a small tent, and as a result the tent is on average about 28 degrees celcius daytime and the plants still get a lot of wind. Looking for whatever advice you can give! :)

Nutrient lockout, ph imbalance or nutrient burn?Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn.
The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.

I'm not adding any extra nutrients. I'm just hand watering with a PH between 6-7 every other day to every 3rd day. I mist them daily though.
