I do two light de-foils; they're due for the 2nd one now that the stretch has slowed. Anything that is healthy, is taking in taking in co2, stripping the carbon and expelling o2; at the same time as "feeding" the colas (even leaves that are shaded contribute). The added transpiration, causes turgidity, which in turn causes the plant to suck up more water and nutrients. This equals more colas and biomass. Even the yellowing leaves are giving up their mobile nutrients.
~95–99% of all carbon in a plant comes from the air
— specifically from CO₂ absorbed through the leaves during photosynthesis.
Only 1–5% of the plant’s carbon comes from the soil, and even that is indirect (microbial inputs, root exudates, etc.).
Plants do not get carbon from soil minerals — they get nutrients from soil, but carbon comes from the atmosphere.

What percentage of a plant’s dry mass is carbon?
A plant’s dry biomass is typically:

≈ 45% carbon (range 40–50%)
This varies by species:
Wood / trees: ~50% carbon
Herbaceous plants: 40–45% carbon
Agricultural crops: 40–48% carbon
So nearly half of all dry plant matter is just carbon pulled straight from atmospheric CO₂.
I know
@Eledin aready knows this, I'm typing for the benefit of others who read this thread.
Plus I'm high af and feel like jabbering
