False reading or Hi PH?

Is 20% humus lombrico mixed in my substrate giving a false โ€˜hiโ€™ ph reading? Or is it truly over the max reading? I got one reading of 7 only at the exact second I took the picture, so I made a video. My water is high in calcium, I recently switched to distilled.

The context of measuring soil pH is difficult. Evaporation will skew it futher from 7 - whichever side it is on, hopepefully slightly acidic. you may need to do a little figuring out as to when it is most accurate.. maybe check it a few hours after an irrigation. Then if you notice certain trends through the irrigation cycle, you know to interpret it better with less than ideal meadurements. You will have to learn some familiarity. I doubt it's an accurate measurement due to mechanics of trying to measure pH of a slurryy of solids and moisture. Some chunk of an amendment resting against the probe could possible cause a false reading? ph what you give and spot check runoff.. compare to your soil readings... gain familiarity to use it in lieau of ph-testing to save time/effort/annoyance. Best to perceive a baseline when plant is super healthy and fast-growing etc. This is well worth the effort since you already bought the soil meter. My 100-pack of strips from 5 years ago has about 20 used, lol. I don't even look anymore. nutes are ph-buffered and one less thing to worry about. go soilless. hit the easy button :P it's a 10g plant either way... safe to experiemnt and not worry about consequences.

Ph meters send electrical signals from one anode to a cathode and measures blah blah between the two. Electrical signals require a water and salt ions. Only way to e sure you are reading correctly every time is to measure in the same context each time. 20 min after watering for example, taking measurements with different moisture levels will give different results. Metre needs to sit in medium for 5 min before the test, then take the test 4-5 times in succession and see if you get a stable reading. Whenever you are done you wipe off the metre and put it away safe from moisture and oxidation. Phosphorus is the most Important nute for a seedling, above a pH of 7 it will bind with calcium causing problems. I also doubt the pot will do you any favors with regard to oxygenation as when pH is in range Phosphorus likes to bind to oxygen itself during uptake. Hummus lombrico won't drastically alter the pH as it's a ph buffer, highly rich and highly moisture retaining sonic won't go well with the ceramic pot for long unless you keep drier conditions. Gluck.

Regarding your profile. Best solution.. get yourself the "guy"? ๐Ÿ˜… Or much better emancipate. You don't need a guy, only if you want one๐Ÿ˜˜ Rock on gal'

Not the answer to your question. Please don't be mad, but I would suggest you don't waste any additional time on that. It has started flowering. With such a dwarf even a reveg would be much slower and probably not healthy at all compared to a fresh start. Edit: seems like an autoflower from an unknown breeder, so no reveg probably. Regarding your question, if you put it in it needs to measure, of course it's changing. Anyway, get yourself some ph stripes and measure input and drain. Cheap electronic devices can measure wrong, calibration issues, and so on. Mixing your own soil is awesome, but if you have issues perhaps just stick with a commercial product. Anyway just start over, even if you love this little one.
