Watering Schedule During Flowering

Im growing using wilma 8 with clay pebbles. Switched to flower 5 days ago 12/12. i am after some advice on watering during the hours of darkness. lights on plants get fed 15 minutes every hour. does this apply during darkness too. Have read that you should only feed half way through darkness then half hour prior lights switching back on.

Will appreciate any advice you have to give

Every hour!??!?! For 15 minutes?!?!?! Whaaaaat. Is that a very very light pump or something? I get away with watering for 15 minutes every 3rd hour in clay pebbles!

Maybe i'm doing something wrong then?

Eh fuck it! it's been working for me for since and never had an issue with over/under watering.
I also water the exact same during day/night. Can you link where you found it's best not to water as much through the night time?
I mean plants do most of the work during the night time..

How are you watering. Are you using the blue sprayers. I noticed a thread on a
forum about not watering through the night. I thought it was a bit strange so thort id
ask. Tbh some of my leaves were browning and crimping and I thort it was nute burn so
i bought a nute truncheon and lowered the ec. But maybe I am also over feeding aswell.
I still have several leaves that are browning. Do the pebbles hold enough moisture for the
3 hour gap you have between feeds. Will over feeding cause leaves tips to curl down and brown/yellow
then turn crispy
