Sure thing. I'm pretty new to growing myself, I'm on my second and third plants now.
When watering, I just stick my finger in several spots and based on what it feels like, I can sorta guess what the bottom must be like based on weight and touch. I am pretty sure that I over-watered my first plant. The plant had really droopy leaves that resemble the leaves on your plant.
They also might droop in anticipation of night-time. I've noticed that with mine and have seen others say it enough.
Dunno though... Do you water till runoff? Maybe try less water next time and wait till you feel pretty dry soil when you stick your finger in the dirt.
I think it might also be a sign of nitrogen toxicity, but I believe your leaves would be darker if that were the case.
