I call it a droop. But before you can see that you have to have good lift, which you do not. The watering properly with a wet/dry cycle will give that to you. A droop starts happening with the lowest leaves about 12 hours before the container is going to run out of water. If you are in veg with a 6 hour dark window and you see that droop starting the day before, let them go their night period before you water again.... and know that the absolute perfect time to water is at the beginning of their daytime.
Anyway, that droop, where the leaves move from an upward angle to less than horizontal will slowly work its way up the stalk and by morning all but the very top should be drooping, if you were in that window. At the same time the droop starts, the plants will start putting out their smell... I call it a perfume pump. An alert gardener with a good nose can smell them signalling for water.
Keep in mind that a droop is not a wilt. Wilting is when the trunk actually bends. This is not good. This is such a severe lack of water that the plant can no longer maintain enough water pressure in the trunk to hold everything up. In veg, even getting to the wilt stage is not a super big crisis, the plants will bounce right back up if you catch them in time, and I guarantee you that the plant grew a lot of new roots while it was seeking out every last drop of water in that soil.
So once you get them in a proper cycle and see daily lifting up toward the light, (the cool kids call it praying) they will signal to you that they are going to need water soon. Right now, they can't do that... but give them some proper watering and they will.
now I have room for all of my 3 plants so should be good to pot the last one up tomorrow
