You also sell B’cuzz Root stimulator. Should I stop using this product and replace it with Rootbastic?

There is no problem using B’cuzZ Root. But you can also use Rootbastic instead due to its high NPK and because it’s an organic based fertilizer. If you use the Rootbastic correctly, you will see a difference in your roots in a very short period of time. For example: you roots will get bigger, whiter, stronger, and longer.
