Glad that it worked out for you.

As I mentioned, some people have used urea successfully with no problems. It is a balancing game in the end.

Plants do uptake ammonia faster than nitrates, as that is their preferred nitrogen source. Theoretically, you could dose ammonia directly for even faster plant growth.
