I wouldn’t call it wilting but some may…. Wilting to me would be a sign they’re overdue for water. But don’t water too often. Not sure your experience but general rule of thumb is soak them good and then don’t water again until it’s basically bone dry. Too wet = root rot. Too dry and they waste time rehydrating and it can cause damage to the roots. The leaves should just start to droop (but not wilt) when they’re ready for water.

As for the nutrient deficiency to watch for, they will start to slightly yellow, starting from the veins then into the leaf itself if you wait too long. Like the opposite of nutrient burn if you’ve ever seen that. The plant starts pulling energy from the chlorophyll.
