That's a lot of watering. In my imaginary experience, the roots get really dense as flowering goes on, and the plants don't dry out as quickly. thus, less flooding was required, weird I know. Funny thing also, they still used way more water even with fewer flooding cycles late into flower.

In fact, this is why many people fight root rot late in flower IMHO, once the roots get so thick they retain water well, the watering regimen that kept them happy before now keeps the roots wet all the time and boom, troubles.

Just make sure that roots aren't still wet right before a flood cycle starts, and that the plants aren't dry and droopy before a flood cycle starts. Thats the problem, their needs constantly change, definately women.
