Can it also be an issue with them all fighting for root space?

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👍😉

Spotted crisp leavesWhat's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.Leaves. Edges burnt

Nutrient problem??? Excess or deficiency?What do you think is the leaf issue?
Open to second opinions.
Most everything stayed the same, except:
> increased water: 2L to 3L per 7 gal of soil
> introduced a bloom booster
> increased volume of worm castings, molasses, mycrobes and ethylene to the tea5y ago
