So when I decided to get into DWC I sound found out I had to monitor the total dissolved salt in my water, so I got an EC and PH Meter. But what is bugging me a bit is the wide range of recommendation as to what EC should be used for different growth stage.
Ie most chart I find online will aim for a starting EC of 0,7 to 0,8 for week 1, and had it ramp up 1,1~1,3 by week 3 of veg. The chart also start flower at week 4? There’s something I’m not getting here.
The few informative post I found, people were using 1,2 to 1,4 EC during flowering but chart is way up at 2,0.
So what gives? What number have treated you well? What’s the biggest factor in the nutes strength ? Does more light can help run higher nutes concentratio? Also for those familiar with PPM number, these are really fine to work with if we know which correction factor your meter is using.
Doing the right thing is what I want, but understanding what I’m doing is even more important
