Your water supply is fine, even without a direct source, there is a small amount of water in the soil itself, same for the basic nutrients like K and P
As you can see you get X amount per minute already
It is possible that the speedup broke some mechanism.
Also in the beginning you can only build 1 thing at a time, if you built too much canopy but don't have enough sugar for it, it will block the root development
With the X you can stop all the planned ones
Try to build 4 roots and 4 leaves in the canopy first
Then when you get some sunlight in, roots are more important
