Dwc 8 gallon bucket, when topping off my bucket through the week should I use just ph ro water, or do I add a dose of nutes to bring the ppm to what I started with?
I check the ppms of what remains in the reservoir. Very rarely have I ever added just pH'd water.
If the ppms are low, I'll top with a strong mix, if they're high, I'll go a little lighter.
