Normal…
Check your ph probe and make sure there is no build up on it, might need to do a health check as well, it’s good to do it every so often. Afterwards I would just submit a ticket support@grobo.io just to make sure everything is fine. She looks okay but I’d rather be safe than sorry, I ran into ph issues later in my flower because I’m an idiot and wasn’t looking/checking the probe so the pH was off a bit which meant it wasn’t absorbing calcium therefore hindering the nutrient uptake. Made the flowering process really slow and she didn’t really fatten up too much. I had to super crop a lot for height issues and was more focused on that than anything which was my fault entirely.
I just see some spotting on some leaves and that’s what my girl had too and then it was too late
