Plants used to high temps? Can I change to better temps now?

[bio1]

Hi!

As long as ive had my plants (3 1/2 weeks into flowering now) they are used to a bit high air temperature ... about 28°C there was constant air movement all the time though

now i read that too high temperatures can highly decrease the yield so i invested in some more air circulation and i can get way better temperatures now (~22°C)

now... can i do this or would this rather damage my plants as they are used to the higher temps?

Should be fine. Had the same problem before and lowered my temp with no problems.
