Don't judge by the runoff look at your plants ,if they look fine and growing normal then your good. I grow in coco and I honestly just check my ph to make sure its in the range of 6.0-6.5 thats it. I hardly ever use ph up or down because I dialed in my nutes and there is a lot of debate wether or not checking runoff is useless or important. Just learn to read the plant regardless of what PH, EC run off says my EC never goes over 1.5 in flower because I inoculate constantly with microbes so they level out the food and PH for me.
Thanks mate. What levels of ec do you maintaine in veg and bloom?

Clones/veg .5-.7 Late veg 1.0-1.2 flower 1.3-1.5 Im growing a indica dominant hybrid strain every plant is different but with this e.c range and microbes I have grown multiple strains and never had nutrient issues
Do
Do you add any calmag?

YES! Cal-mag is a must in coco especially with filtered water. I use about 3-5ml per gallon every nutrient feed its also recommended to flush with cal-mag light dose because if you flush with plain water in can mess up the cation exchange because coco like to hold on to cal-mag and won't make it available until the its at full capacity
Do you use ro or tap water?

Here is a link to my intro thread I post a pic of my nutrient line up and the coco I use

Doesn't that just mean your plant has been feeding on the nutes you just gave it?

No i don't ,I have chlorine/chloramine filter with a carbon scrubber . There is a few brands but this one was the only one available at the time. Get R.O filter if you have well water,or hard tap water but using a filter for coco is important in my experience
When I tried nft I was told if ec goes down add nutes, if it goes up add water. I was wondering if it was the same.

Ive never done my hydro like that, when my res would go down I never measured EC or PPM I just added fresh PH'd water and changed res each weekend. Works like a charm.

Yup Thats how I do my plants I have a drip system that does drain to waste, 20 gal rez it last for about 5 days then i just top off with fresh water for the last 2days of the week, then change the rez its kind of like a weekly flush in a way helps with coco for salt build up and overall quality in the end

That's exactly what I do , clean fresh R/O water only for flush 2-4 days only any more loses flavor.Yup Thats how I do my plants I have a drip system that does drain to waste, 20 gal rez it last for about 5 days then i just top off with fresh water for the last 2days of the week, then change the rez its kind of like a weekly flush in a way helps with coco for salt build up and overall quality in the end
