Honestly, I would skip the Koolbloom altogether if your plant is healthy and your soil is in good shape, especially if you're working with a good organic/living soil. Alot of the timing of the plant has to do with genetics, anyhow. What strain are you running? I ran a haze strain a while back that took almost 15 weeks from the first sign of pistils.
I have many strains atm. Working through them to keep the best ones. But your right sativas take longer to ripen and the ss is living. But i just buy new ss everytime so if i kill off the soil it wont matter. I wouldnt start dry kb till week 8. Which should force them to ripen faster plus low stress should add flavor. Rather start fresh everytime then try to doctor the soil up to re-use it. Then end up with a bad yield cause i didn't doctor it up right.
I'm new to ss n fogponics. But its a fun learning process.
Though....if not harming the ss it would still be healthy making for a great outdoor veggie garden.
Have read in forums that syn nutes don't kill micro organisms. Was said only thing that does kill the ss is if you use to much not flushing weekly making it too salty. The salt build up over time harms organics. But not nutes themselves. So I've heard. Again could be just a religious belief without facts. But is what i read. Also heard you want to kill off plants at the end. The harder hit at the end the better the flavor. So ive heard. Its not like an ever bearing plant where you want it to produce again.
But again ty and have an awesome weekend!
Think I will try it on a plant or two to see.
