CO2 deficiency...????

We had several momma's that were in a neighbors space. These momma's had swolen stems, that looked live 1-2cm (1/2-1" long) blisters on the stems, and after looking at the space, it appears that the grow space was devoid of fresh air. These plants looked sickly and like something was obviously wrong....????

Will a lack of CO2 cause this????

We moved these into a new space and things have changed, but I'd like to hear some opinions on this.

Muchas Thanks!:thumbsup:

Got any pics handy? :)

Sorry,

I don't have any pictures:( , but these stems look like swollen pole beans.
