Hello. In the back of my Advanced Nutrient catalogue it has charts that are up to 2000 ppm. I usually do 800 to 1000 ppm in veg and 1200 to 1400 ppm in flowering. At 1600 I usually get some leaf tip burning and huge buds.. Chuck.

Measured EC and burned leavesI defoliated my plants yesterday and i gave them some plain water (corrected to ph 6,5) …. I took 5 plants which are about to be harvested and measured the EC: it’s between 0,88 Ms and 1,17 Ms…. Quite low but plants aren’t burned that’s strange ! What do you think it’s happening?

Hard water vs CalMagI don't have EC/PPM meters, but I know that I have hard tap water, according to my city water distribution company. Do I need to suplement CalMag on my feedings? How much should I use if I don't have PPM meters here? What are the risks of using or not using CalMag in this case?Week 1

Beginning of Week 2 - Yellowing? Over/UnderFeeding?Are these first leaves showing some yellowing or is this a normal shade for leaves at this point. Just wondering if I might have overfed the plants, or even the opposite. If anyone was able to share what they think it would be extremely appreciated.
