Rockwool ph/ ec rising

For the people who have experience with growing in rockwool, is it normal for my runoff ppm/ ec / ph to rise?
If so, what should I be looking at for a normal/ acceptable range?
I just started some rockwool clones in the 6x6.
I originally had the cubes soaked at 5.8-5.9 ph and around 1.6ec.
When I checked my runoff today (it’s been 1 week since I soaked the cubes) my ph was 6 and my ec was 3.4. Is that normal?
I thought I read that if the ppm/ ec shoots up higher with runoff than that...

How concentrated to make Nutrient Solution in my 13 Gallon RDWC Reservoir for One big Plant?

I am modifying my Power Grower RDWC systems to have a 13 Gallon Reservoir. And in general my tendency has been to make my PPM stronger then what they actually consume nutrient wise! I have done this because they don't seem to burn and because they can consume the whole entirely of the reservoir in one day at their peak flowering cycle. In Veg my plants can drink as high as 1400 PPM which seems crazy. But as soon as I flip the light cycle this drops to about 600-700. .5 conversion And I...
