So I was wondering when/how/quantity of flora series trio i should be feeding to living soil. I read around that i should start giving nutes after a month or so (40/40/20 FOX FARMS OCEAN , FOX FARMS, HAPPY FROG, AND PERLITE )
Your soil will carry you all the way to the flowering. Unless you go for a really long veg. It'll feed for 5+ weeks. Monitor run off ppms if you want more accuracy and begin feeding her based off your schedule compensating for what is in the soil and what week you are on. So 50% once you're ~800 ppm runoff. Since she'll be a big girl by then or be calling for more than 800. She'll let you know.
From experience using the flora series do half the recommended dosage. Its really potent and super thick so make sure you mix it alot. As far as when to start giving nutes your soil should have plenty to carry your plants into middle veg.
