My 5 girls are growing in a bathroom in Greentree Ultimate Blend super soil. I didn't realize it was considered a super soil until I was already committed. I've been watering distilled water PH'd to between 6.5 - 6.8. I came across an article that said not to use PH up or down in super soils, They all seem to be healthy at the end of week 3. Should I change to straight distilled water and not worry about the PH?
