new Setup! nice old & newschool strains

I Grow with Flo Living Organics. I tested my PH Level of my Soil today and it was around PH 7… Normally, flo is known for the fact that you only have to add water and the ph value regulates itself. I think I may have made the mix a bit too strong for the stadium. I thought my plants could handle it to be honest. how would you proceed now? maybe make the water a little more acidic and hope that the ph value in the soil will regulate itself again?
