mog- attempted to access the website but couldn't... when will it be up (curious to run the coir)?

Glad to hear another who believes in preflushing... currently under the CCGro & get initial run-offs @ 760. Highest have been with Canna @ 2000+. Also cut with 20% chunky perlite, so interested in the S1 to avoid this step.

Have issues with continued pH drop to 4.5-4.9, where it stabilizes. This is initial flush of appx 4x media volume- always pH's to 6.0. It just drops & drops with each flush until it bottoms out at listed above. Any ideas on why this is occurring? How does the coir you listed balance out?

Thank you & best!
