That looks like hydro to me so your very first problem would be that your ph is too high for hydro apps. It should be no higher than 6.2.....5.6 beng ideal imo.. Yes, your ph is abnormal enough to kill off your plants by creating "less than healthy" plants.. Second, let me ask about your home water filter. How is it filtering your water.....through some sort of sodium? Most home filters do and the resulting sodium level is too harsh for cannabis.
