The solubility of CaCo3, MgCo3 in water at a normal pH is VERY VERY low.if you currently have a Ca or a Mg defficiency and want to fix the problem right away you should be using a highly soluble form as in kany of the CalMag hydroponic solutions on the market.you add powdered dolomite to your water its fast acting and effective. my ph meter i think is off as well and as well all know dolomite has trace elements of mag
if you can believe it, it was underwatering
so after all that and a 3-5 undeciperhable pH its all cause you did not give enough water ?if you can believe it, it was underwatering
Oh but there's a major difference between those crappy moisture meters and the tensio meter I'm talking about. And no, not even the most experienced grower out there can beat this tensio meter by feeling the weight of the pot throughout the entire cycle.those moisture meters are pretty cheap, like under 10 bucks at home depot, but honestly, after a few weeks of using it, you can easily get a good feel by the weight of the pots for when they need watering.
Yup, suprisingly.You gave them more water and they perked back up?
I'm using a cheap meter that measure p.h., soil moisture, and light all in one. I don't think its very accurate anymore so i'm going to try something new. I appreciate the info!Oh but there's a major difference between those crappy moisture meters and the tensio meter I'm talking about.

It's like an artificial root and anyone who grows on soil and uses it won't ever grow without it again (but instead buy one per pot so you don't have to switch, you'll earn it back easily per plant, plus you'll save a load of water). It's a game changer especially for beginners (so they don't spoil their first grow by over watering as most do). So many people looking to increase their yield using various (desperate almost) measures while optimal watering makes all the difference - start there.

I'll shut up about it now because I mentioned it a few times in these forums already and a. I'm not sure they are delivered (at reasonable rates) to the US and b. I don't want to sound like I'm advertising their stuff. It made a huge difference for me and many others (fairly standard equipment in Dutch growers forum since 5-6 years).
