I’m on week 6 today. Is this a good TDS reading or should it be higher/lower? I have the unit set to 500 ppm . I used 5 ml/gallon of tiger bloom, 2 ml/gallon of bud candy & big bud. I also added 1 tbsp of epsom salt to lower the ph in my soil.
1150 ppm its ok for flowering.
Your plants have P deficiency - and this combination will help you.
But this mixture is not for permanent use.
If I were you, I'd rotate this with your old solution (formulex)
One time - feeding with tigerbloom. Next time - Formulex.
