I've been experimenting until they fix the irrigation problem. First farm I did I clicked save after I was done with everything. then reloaded the game. A portion of lettuce didn't water.Sooooo, the next farm I clicked save after tree harvest, save after flower, save after each harvest and planting of a crop,save when I changed to another crop and on and on. Clicked refresh farm, then refresh whole game. Went back to farm I was on and watered, did this to 16 farms

but they all watered. I have nothin but TIME!!!!
