Ok you need to get an EC meter because even though you have volumes it does not give you the strength in numbers to compare. I would not feed Autos over 650 PPM not counting your starting water. The frequency of feeding makes a big difference also. I think feed, water, water, water repeat. Is a good place to start.
Nutrient schedule was gathered from:
I will switch the schedule to what you suggested feed, water, water, water, repeat. Also, how much run off should I have in the bottom saucers?
Okay so your 5ml sensi Is really concentrated so definitely use less additives and cut down the dosage. 5ml is strong And you should use an EC Meter to see how strong ur feeds are first. I never go over 1ml per litre in coco with sensi line up
I plan to purchase an EC meter. I was thinking maybe getting:
Bluelab PENCON Conductivity Pen and Digital TDS Meter, Water Tester for Temperature and Nutrient (CF, EC, PPM 500, PPM 700), TDS Testing Kit for Hydroponic System and Indoor Plant Grow
Amazon product
Does anyone recommend a different EC meter?
