Does CO2-enrichment cause oversexed stigmas? (relating to hairy buds)

[brolex]

[FONT=&quot]Greetings, everyone.[/FONT]

[FONT=&quot]Seen here are buds off of a 50/50 hybrid plant that was flowered for almost 10 weeks, when the breeder specified an average of 7 weeks. Trichomes are mostly cloudy, with a slight amount of ambers. Grow adhered to VPD, with day temp of 73F.

[FONT=&quot]I am curious if CO2-enrichment (1500ppm to 1800ppm) could potentially cause mature buds to possess thick, voluminous stigma hairs?[/FONT]

[FONT=&quot]I honestly have not ruled out if the pheno is sativa-leaning, or if the plant was harvested a bit too early.[/FONT]

These are budshots taken at end of week 9 of flowering:

I am asking because the calyxes did not seem to visibly swell up even after flowering for almost 10 weeks.

I found Sat/Sat leaning don't swell up as much, under normal circumstances. So I don't know. I do long veg (8 weeks) and bloom until cloudy with only the odd amber, most of the time a couple of weeks longer than what the breeder recommends.

In my experience CO2 enrichment does not detract from quality.

Breeder's recommended flowering times are usually wildly optimistic at best.

Over-fertilization can be accumulative and leads to acidification of the soil and a generally toxic environment for the root system. Potassium uptake is limited and the calyx never swell and "ripen".

When ammoniacal nitrogen predominates and accumulates it can exert a hormonal effect that favors vegetal growth over the normal flowering response, hence the re-flush of stigmas...
