Flowering, do i change nute & water ?

Hi all so my plants starting to flower and i was wondering if i had to change the water & nute schedule.
I know i have to change the nutes to more phospurus and potassium so i got some of that but with the watering do i give it more water or less. And also do i give it more flowering fert as well ?
Currently im growing outdoors its pretty hot and dry where i live average during the day is around 26 degrees and i get about 14 hours of sunlight. I give it water everyday and i give ferts every second watering so is that too much ? Because the instructions at the back says give it once 2 weeks but i went with every 2-3 days and my plant seemed to be healthy. Soo yea any help would be appreciated
Thanks in advance

The only real difference you may notice is that it will possibly need more watering/feeding during flower. The plant uses more energy creating the flowers than it does just leaves. Keep an eye on it for a few and see how things look. The plant will tell you if it needs more water or less, same with ferts.
