Please help me ID this rot

I use 2 tsp. Agrifos in 1 gallon of distilled water. You usually need to add at least 1 tsp. of pH UP as well. Once you've done that, you need to check your pH level to get it to 6.5. You may need to add more drops of pH UP. I usually add it 4 drops at a time and keep testing the pH to see where it's at.

Write down how much pH UP you needed to add to get it to the 6.5 pH level. That way, the next time you use the Agrifos, you can automatically start out with one tsp. of pH UP plus the amount of extra drops you needed to add the first time to reach 6.5 making it quicker to use in the future.

If you end up with too high of a pH, you then need to add pH DOWN. I have a waterproof pH meter which I use to check the pH on all of the chemicals & fertilizers I use on my orchids.

Let me know if you have any more questions.
