Oh shit... my bad. Mine isn't ghe...I got silica blast. Mines liquid form. What schedule do they recommend for that product?
GHE recommends 4gr/10l; I put half a teaspoon in 5l. I'll see; it's still as opaque as ever.
Same for the big tank, I put a good spoon for 25l. I will buy a scale ^^
For the initial problem of the topic that I also had, like a brown deposit all over the bin, I proceeded by elimination.
For my clones, I let the water rest, then added the micro, grow, bloom, then ph-; I left more than 24h, no brown trace, I diluted the proroots in water I added today, nothing for now, I'll see tomorrow.
I really don't see where this deposit comes from outside the proroot or the heat of the water. It has been at 19/20°C for 3 days; it was at 21°C 21.5°C before.
I will keep you informed
Thank you for your help
