Is my EC ok for plain water?
Faegrowsstarted grow question 4y ago
Stupid question but the EC on my meter is it 0.3 or 3.7? I never really minded the EC just ppm as I grow in canna Coco plus but now I'm wondering if the EC is actually right. PH is usually 6.3-6.4.

It means your ppm is about 185ppm 0.37.
500ppm is 1.0 ec. 1000ppm is 2.0 ec Take your ppm and double it. This is the hanna reading.

So it’s not bad for tap water.. anything above .4 EC would be worrisome to me.
And yours is .37

Nitro toxicity and calcium deficiency. Should I flush?Little pas halfway through flower and appears I have nitro toxicity, could this be a cause of my calcium deficiency I have been dealing with? Should I flush it or would that continue the degradation of the calcium?

EC and PPMI read about EC and PPM. I have a meter that reads both, and it says my PPM is too low, and the number it gives for EC is like 1200 and the charts all have numbers like 1.2-2. WTF.
I ran out of pH strips but I know my pH is good, I used distilled water. What's everyone's thought?Week 7

Watering question - Volume?Currently doing my 1st grow and had some watering questions. I see a lot online about when to water which seems pretty easy to understand but I have trouble finding the amount of water. Is it based on the size of the pot? or the size of the plant? or both maybe? How much?Week 1

TDSI’m on week 6 today. Is this a good TDS reading or should it be higher/lower? I have the unit set to 500 ppm . I used 5 ml/gallon of tiger bloom, 2 ml/gallon of bud candy & big bud. I also added 1 tbsp of epsom salt to lower the ph in my soil.Feeding. Chemical composition
