Is my EC ok for plain water?
Faegrowsstarted grow question 5y 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

Compensating for Effect of Supplements on PPMI decided that my girls probably had a calcium deficiency from using distilled water. I added a cal/mag supplement and an enzyme supplement. Now my PPM is through the roof. Should I reduce nutrient levels so that I'm still in the desired PPM range?

Liquid OxygenWould you all use this in your water when trying to give oxygen to the roots? I’m noticing some really dense, not drying up that quickly soil so it’s making me think that they can’t breath. I don’t know, just making sure every part of the plant is happy & healthy.

Time to Start FlushingHey guys, I'm writing because I have one mature plant and I'm doubting if it's a good time to start flushing it. Trichomes are starting to look cloudy, but still many are transparent.
Do you think it's time to cut off nutrients ?
Thanks and happy growing !

Nurse
wet/dry cycle from RQSRQS suggested this wet/dry for Auto.that's okay?for irrigation, when he said 1.5 liters for each day, that means I have to water the plants every day? or is it better to have 4.5 water once every 3 days?And that the amount of irrigation he suggested for 11L pot is not too much?
