Just common water from the tap. You just need to let the chlorine evaporate and let it sit during 48H before using it.

High ppm in drainage
I flushed coco two times with 8-10 litres with CalMag (200 ppm) and it does not help. You can see in my comments to the last weeks of the diary that it doesn't matter how much ppm I water the plant, it is always 2-3 times more ppm in drainage.What should I do?

TDS
I’m on week 6 today. Is this a good TDS reading or should it be higher/lower? I have the unit set to 500 ppm . I used 5 ml/gallon of tiger bloom, 2 ml/gallon of bud candy & big bud. I also added 1 tbsp of epsom salt to lower the ph in my soil.

Good Nutrient Mixture For GH Flora
My outdoors are transitioning and I got GH Flora Series (Micro, Gro, Bloom). I mixed 2.5ml of each into 1 gallon of water (4 L) and spread that across my 4 plants. I feel like this was too little? What is a good general mixture for 1 plant, or is it better to make a bigger batch?
