ya its not recommended but if it is a must and you got something for flowering i would say the beginning of your light cycle so it gives your plants a chance to absorb/dry out what you sprayed on them. anytime you spray/mist your plants try to do it in the beginning of your light regiment. btw whats the name of the stuff your folier feeding during flowering???
