Questions about PH

[fhydro]

Hello,
after putting some seeds into rockwool cubes, there are now in a bubbler system. The roots are growing fast but the leaves seem to be stopped. I checked my PH solution : 9!!!. I made a new mix which is 6.5 PH.
1/ Is it normal to experience a slow growing in a 9 PH solution ?
2/ Why the PH is increasing so fast ? Is it a rockwool pollution of water ?

Thanks for advises
