@bobbi @Countryboyjvd1971 is one of my friends here on ilgm and he is very knowledgeable. He has a bit more experience with the nutrients and I'm hoping since I tagged him he will come back by and explain his water water feed technique so you can understand what he means.
Don't worry too much about the pH and TDS numbers right now.
I'm happy with the going in numbers on both pH and TDS and I'd like to have you do the reading again next watering. I'd like you to use the format of
Strain pH TDS
I'd like to see if there is any correlation between the different pH and TDS with the different strains.
