Hello guys hope you're good, I'm allowing myself writing this post cause I just started growing in dwc (used to grow in soil) and would like to know some things about it. I'm growing with Metrop fertilizers (I'm using MR1, MR2, Root+, Aminoxtrem, Enzymes, Calgreen) using tap water in a 10 liters bucket, my air pump is boyu u2800 which seems pretty weak to me but I've been told it's enough for a bucket this size.
If anyone can answer some of my few questions I'd be grateful :
-My tap water has "high" TDS (0.4 EC),is there any "cheap" way to lower it other than RO (if it's important) ? How should I calculate my EC for my plant, should I act like I start from 0 EC ?
-The EC in the bucket increase even tho the plant seems to be "healthy" and eating good, why does EC increase and how can I make sure my plant still has enough nuts in the water ?
-I've noticed that PH tends to go up in my bucket, is my ph meter accurate and why would it go up ?
-Last question, my plant has orange/brown spots on older leaves on the bottom of the plant (see pictures), maybe anyone has an idea of what it could be ? (I'm thinking about calcium excess but not sure)
Thanks a lot for your answers and knowledge,I hope my english is good enough for you guys to understand and wish you a nice day.
