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.

With 1 gallon pots do they work out well with 12 weeks of flowering?

Check these Ace Panama harvest pictures at 12 weeks. 1 gal pot from seed to harvest, but I was feeding her every watering in the flower.

I would switch when you flip because you are using an organic fertilizer that's slow. Nitrogen is a flowering hindrance when it's given in excess and can will slow the flowering hormones florigen or florets way down. There is a downtime between veg time and flowering time when a plant changes stages. If the nitrogen is kept high longer then the flowering hormone will slow way down.

Vegetation hormones refer to the group of plant hormones that regulate general plant growth and development, including stem elongation, leaf growth, and root development., while flowering hormones specifically control the transition of plants from vegetative growth to flowers with the primary flowering hormone being known as "florigen".

Key points about the difference:
Function:
Vegetation hormones manage overall plant growth, while flowering hormones trigger the initiation of flower development.

Examples:
Common vegetation hormones include auxins, gibberellins, cytokinins, and abscisic acid, whereas florigen is the primary flowering hormone.

Regulation:
The balance of different plant hormones determines when a plant transitions from vegetative growth to flowering. Google

Give your plants some nitrogen downtime between the two stages instead of excess. High nitrogen during flowering promotes diseases like mold or blight. Good luck friend.

How long is the downtime and how do you feed at the downtime? Or water only?

Keep the nutrients going just switch when you flip and the plants will do what they do best.

The general consensus with the bio canna line has been to use the vega until stretch finishes, then to switch to the flores. There are a couple threads on it here and canna themselves have recently started recommending that method as well. The NPK levels of both nutrients are the same but the source of nitrogen differs between the two. In most organic growth applications you should be feeding the soil in order to feed the plant, but given the small container size you are limited to, it may pay to switch earlier, for the reasons stated above. If you can I'd try both methods on 2 plants and see which works best for you.

Got some grows with the bio canna line and when i did i hard switch from vega to flores 1/2 strenght i got ca deficiency. I usally fed every other watering with tab water. No measuring of anything, just look how they react.
Most of the time it was 9-10 weeks sativa dominant hybrid clones.
One vega feeding after flip, the next feeding 50:50 and then what ever the strain could handle from flores. Low dose p/k starting around week 4 and only water for min 2 weeks at the end.
That worked most of the time good for me.
