Quesion about H20 on timer(s)

I have my reservoirs for my hydro setup on timers. Recirculating Dutch bucket systems with quarter inch tubing (w/ ports) going around the base of plants. For veg I let run 24/7, and currently in bloom @ 6AM-10AM....then 7:30PM-10:30PM. Feeling like I am watering a bit much (my guess). I was wondering what you all think...and what sort of timer increments you would use for veg AND for bloom? Please share and THANK YOU in advance!

I did both in a similar and found both work well. I had less issue with a few 3 minute squirts a day. You can check the rocks underneath and make sure still damp. My timer failed for days till noticed and plants were fine in the wet rocks.

Thank you so much...very helpful (and what I was leaning toward doing, so confirmed).
THAT SAID- what should timer be set at for Veg? 24/7?

Probably better off giving them some down time.. I used to use rocks but switched to coco because it is, or can be, much more forgiving.
Took me completely frying a few flowing plants to decide I wanted to switch..
If your ever looking to switch, Coco works awesome
