1st time grower here. I have some autoflowers in pots and I can’t get the soil’s PH down to at least 7.0.

1. I transplanted the plants into their final home on Thursday.

2. I added one dose of ph down with Bio thrive grow and Myco+ on Friday and of Sunday night it did not make a difference.

3. On Saturday my delivery of CalMag and ArmorSi arrived and added them to the watering.

4. The soil’s Ph level is still closer to 8 than 7.

5. I am using a Sonkir triple meter for the soil testing.

6. The plants are having some discoloring and worried it’s because of the Ph levels.

How do I quickly lower my PH without burning the young plants.

I planted them on 4/20.

Thank you!!
