Is this normal after 8 days?

Yes she is to wet, you can tell then by how the leaves are curling into the stem. They should be more flat and laid out like solar panels catching the sun. I would lay off the water for a bit and then go back at it. Everything else is looking on point. Congrats!

The temp is perfect, the humidity is perfect, but the pH is a bit too low... I'd raise that to 5.5-5.8 and she should really appreciate it. It can go as high as 6.5! It's just a little TOO acidic for her. I can't see if the rockwool is too wet but you might check that... if it is, just raise the cube a little bit in the pebbles so just a bit of it is in the water... this way, the roots will still get constant nutrition. Good luck - it's exciting to be at this stage of the journey - enjoy it!
