Middlereefstarted grow question 5y ago
I’ve just recently bought a blue lab EC pen and I tested my nutrient feed which came to 0.8 EC & temp 24c then I tested the runoff and it came out as 1.0 EC, is this a good? Any info will be great as this is my first time testing for EC.

I started testing my runoff too after many lockouts. From what I know, it's not a good sign. It could mean that salt build ups have formed in the root zone and have been dissolving in the water as it passes through the soil. If on the contrary, it was lower, it would've meant that the nutrients stayed in the soil, a good sign. I now give water twice before feeding and don't seem to have that problem anymore.

PH measuring for Organic GrowersIf I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.
