Your low temp and low humidity might not be helping¿

Temps i get, i thought humidity needed to be low during flower?

Most people have low rh to try to avoid mold, 

but such low humidity isn't ideal for the plants. 

For 28°C I'd look to have humidity around 60% 

Make sure you still have plenty of air flow and keep the humidity lower at lights off, 

this is when my rh usually rises. 

 

Hope this helps,

it could be something else though?
