@Angiebaby is pretty spot on. The biggest cause of the droopiness I believe is in agreeance with some of what she said, as the pod may be too saturated at this point which could be cutting off some oxygen to the plant. This is one of the main causes of drooping or wilting look of the leaves. The Late Vegetation water level can cause this sometimes as it’s back to High fill now, which will be much closer to the pod.
Another thing to keep in mind is that there might be an issue with your pH probe. Sometimes they don’t arrive the way they should from the factory.
I would possibly suggest sending in a support ticket to Grobo to have them take a look at the pH probe and what it’s reading on their end:
How does Bottle #1 and Bottle #2 look so far? These are the pH up and pH down bottles respectively which the Grobo monitors the use of hourly. Can you post a picture of those just to make sure one isn’t being overused this early in the grow?
As far as your tap root – sometimes they become stained from the nutrients (most of the time actually)… Sprouting little baby roots from the main one is completely normal and will start to build the strong root system for your plant in that manner!
A picture of the roots/reservoir would help us diagnose any issues down there, though.
