Feeding sativas with Canna Bio line

Tranquilidade

I'm working on mastering the growth of sativa plants using the Canna Bio line. While I can finish my plants, I notice some yellowing when I switch from Bio Vega to Bio Flores. I use rainwater and supplement with Biobizz Organic Calmag at 0.2–0.3 EC with every watering during flowering. My total EC during flowering is around 1.2.

I'm curious about how and when you transition nutrients if your plant has a 12-week flowering period.

I assume you are fertilizing one day and then watering a few days before feeding again. If you run a low dose and feed with every watering you can maintain a steady growth.

My pots are 1 gallon from seed to harvest, so I must feed them every watering in flower. Some say they keep Bio vega almost till mid flowering, so my question is do they use only bio vega till mid flower, or 50%/50% of bio vega/bio flores or any other ratio.
