I am in rock wool. I think it holds more water than whatever you are in? 9 days may have been too long. I still have ~30% water in the blocks after 9 days. The 6" rock wool cubes hold almost a gallon of water to start!
After about seven days I start hefting them in case they get light faster than normal. I have gone as long as 11 days before the first fertigation to 20% run-off. Then I wait about 5 days to start daily fertigation to 20% run-off every day til harvest.
