lack of CO2 won't stop it from flowering
This strain can take 9-10 weeks to flower so you have plenty of time still. When did you start to see preflowers forming? From the pics you might be at week 2-3 so she looks perfectly normal to my eye atleast. The buds start to really develop after the strecth is over and after that they will start to swell and ripen.
Happy growing
