You should never leave a pH meter in distilled water. The glass bulb contains the reference solution of potassium chloride. There's two electrode and one side has the KCL reference solution. Vinegar solution works better to remove oxidation.Meaning what, the device is cooked?

@bluter , I've got a pH meter question for you.
I dug out my meter that I haven't used in months (going on years). The display was fading so I changed the batteries, and figured it needed recalibration after doing so, so I mixed up the 6.86 solution and tried the meter. The display showed dozens of different readings for a few seconds before settling on 00.00. I turned it off and on and got the same result.
The directions said if it hadn't been used for a while the probe can dry out and the fix for that is leaving it in distilled water for a few hours.
Are my results way out of bounds or is this normal for an out of service device, and will it come around after soaking?
i always use a kcl storage solution. even then if it dries out i use that to re hydrate the bulb. then i'll check it in RO water, i don't use distilled as it can cause other trouble. i also have calibration fluids, if i suspect a problem i use them to recalibrate the meter.

That's why you leave it in KCL or potassium silicate solution to keep the electrodes intact and not get oxidated/corroded.
Cheers!
maybe not but i'd listen to @Wastei. if you can i'd get some kcl solution to soak it, it should be available at a local grow shop if you can't wait for internet delivery.
in the mean time use RO water to soak it. i wouldn't use distilled to soak it, and never use a ph or ec meter to measure the distilled water. they can't do it proper and it will mess them up to the point of no return.
Rinse the storage solution off the probe with distilled water but definitely don't leave it soaking in it:Thats good to know. Because everything I've ever received states the opposite.

On my bucket listyou'll see that on cheap probes. usually the ones that are like a usb stick. a lot the mfgrs don't really care about them, or the growers really. the better ones will even come with the storage and calibration fluids included.
this is my apera 60series ph probe.
i have a larger bottle of the kcl to refill the smaller container when needed.
it's good to stick with a proven brand as well. hm, hanna, apera, blue lab are all good.
On my bucket list
Looking good and thanks for the heads up on the lighter color, but yours might green up when they hit the res! Tokin Roll's are a lovely shade of green.
Yeah, mine were leggy and pale then got the stripes on the leavesi checked mine, they are on the res now. everything is going on under the perlite lol.
in the other threads they have a definite heavy feeding pheno that wants more calmag. usually presenting in mid veg. but they always start a bit pale from go.

About week 4 suddenly started getting bushy, shoots all over [nb I powered the light up]
Now full feed, 2x CaMg and the colour is improving
Color and growth are both looking great!
