Plants drinking less after flush?

Anyone ever have this happen? I'm just curious, I flushed my plants on Friday with clearex and put them into flower yesterday. Before the flush I was adding about a gallon of nutes/water into each bucket per day. I just checked for the first time since Friday and barely had to add any water Is this normal?

For the record I'm doing DWC in 5 gallon buckets. Any help would be cool, thanks

No one ever had this happen before or am I posting shit in the wrong section again?

We noticed our plants started drinking less when we put them in flower too. We don't water them every day though.... we lift up the pots and when they're light (usually 2-3 days) I give them two coffee pots full of water and let it drain in the shower.

I water every day except the day after flushing. Works for me .
