Can someone explain to me what determines when a plant becomes very dry? I watered my evolution fruit plant last night after 10 pm. I woke up this morning around 12:30 and it was very dry and had lost a grade. I put the watering fertilizer on the plant, so it should have had a little over 17 hours of water. It went only 14 without water. I thought the the watering time had to run out for the plant to become very dry, but maybe I am misunderstanding. Some of my pumpkins had also become very dry but curiously, one of them did not lose a grade.

To me, it's almost like my plant isn't recognizing I put the fertilizer on it.
