Water Schedule for Flowering with Hydro

Guys i just started flowering my 4 PPP purple power plants. They are looking good but Im wondering about the 12/12 light cycle. We are using an ebb n flow system with a 25 gall res.

We have been watering 6 times a day during veg and it worked wonderfully.

Should we just water 3 times a day for the 12 hours Light on, then no more watering until the light returns?

Any advice would be awesome thanks guys!

rock wool or clay pebbles?

No irrigation when lights are OFF. Flood one hour after lights on, and two hours before lights off, and once or twice in between.

HTH

Im using clay pebbles if this helps

hey guys~ what about using rock wools?
