Hey!
I checked out your diary, you actually have the PERFECT conditions for flower.
21-24C You could even raise the temps to 26 day time and it would be no problem but 24C day time is great.
Also your RH is at 50% which is good, if you want more trichomes product taking the RH down to 45% then 40% in the last weeks help to give you those frosty buds.
You've got the temps down, now take that RH down and you'll be amazed with the results.
keep up the good work!
Good luck and happy growing!
