definitely, if not more.
environmental factors change? humidity? temp? too much negative pressure? this will impact how much the plant drinks. It's just getting much larger than before, my guess... growth is exponential, initially. you are hitting the steeper part of curve now.
Give a bit more on next irrigation and see if that gets you back to the wet-dry cycle time you want. can slowly give a bit more and get back to the same balance you had before
