I haven’t used advanced nutrients Organics but I do use other liquid organic products. They make the organic mixes acidic so that the product doesn’t go bad.
I have fed my plants with the mixed organic fertilizer with a low pH and it didn’t seem to affect the plants. I have also raised the ph to be around 5.8. I’m not sure if the pH matters with organics like it does with chemicals. If you have a potting mix with good microbial life, the microbes should buffer the ph for you. With organic mixes, you are mostly feeding soil microbes who break down the product to make it available for the plants to use. Chemicals feed the plant directly. You can measure the ph of the run-off to see what the ph of the soil is. If it’s around 6 you’re fine. If it’s very low you will need to correct the nutrient mix before watering.
I’m interested to see what others say about this. Good luck.
