Hey Buzz, so you're just using molasses water?

For ph, I just did a test run on 1 Gal of the water being used.
Everyone's water is likely different.
Add an amount that you can use as a scale.

example using vinegar:
-Tested ph before = 7.0
- Added 1 tsp vinegar and mixed well. tested after 30min = 6.0 - 6.1

So for me, after i add all nutes, i know 1 tsp/Gal will drop the Ph about 1 full point.

Always heard against using molasses in hydro, got any pics to settle the dispute?
