Afternoon fellow UK green thumbs! I am new to this forum and growing as a whole. I was wondering if someone could help me out with nutes for my DWC grow that I have just started. I am running a 20L bucket with 16L of pH 6, EC 0.8, PPM(500)-400, currently, this system has an auto Dos Si Dos seedling that is showing a root at day 5 from seed. So far for the reservoir I have only used ROOT!T and plant success orca as specified, but since my tap water is 80ppm and I'm planning to switch to base nutes schedule in week 2, I was not sure whether I need Cal-Mag in addition to the nutes I am using. Any recommendations are gladly welcome.
Nutes I am planning to use:
Growers Ark Grow A+B
Growers Ark Bloom A+B
Growers Ark Extra Traces
These will be used according to the schedule provided
Thanks in advance!
