Yes ec is mS/cm and the ppm conversion is using a .5 scale. MicroSiemens per cm is μS/cm Happy Growing

Rock Resinator
Opinions please!! Reviews on Rock Resinator nutrients ?? Anyone used it, does it make a difference to bud density. I’ve been gifted some and have since found out how expensive it is.. Should I believe the hype on this Product? Also heard some rumours it’s bad for you? Any advice?

Shall i add these nutes?
I've seen good reviews for these Vertafort Bloom Tablets (i think they are equal to RQS Easy Bloom Booster). Do you think i can add them to my mix? You can see my setup in the image. Plants are quite good except very few old fan leaves turning yellow/burned. Thanks

Good PPM for feeding Autos, 2nd week flowering.
What's a comfy place for me to be for PPM for nutrient feeding for Autos (2nd week flowering)? Currently for the chart I've been following I end up at under 400PPM but have been bumping it to 450. Can I go a little heavier?

When do you stop giving nutrients?
Pictures taken 3 weeks into flowering. Its 3.5 weeks now. Started as pretty basic potting soil, most of the nutrients im sure are gone. When do you switch to just pH corrected water to feed? Thinking 1 more week for my yellowing plants, and less for my very green one. Thoughts?
