Adjusting PH

This is my first grow so I dont know much about nutrients and PH and stuff like that. I went and got the 3 part Grotek gen-x plant effects and mixed it according to the instructions, but the PH is around 7 and the bottle says 6.2-6.5. I was going to add some fishtank ph-down stuff, but I dont wanna hurt my babies. Any advice will be greatly appreciated.

fish tank ph down is what you want add nutes first then add ph down and if it goes too low then add more water and it will go back up so you dont needx to buy ph up thats common sense but some people dont understand that so they buy both up and down

hope that helps ya bro

yeah.. the fish tank stuff works just as good...

Any thoughts about using the liquid pH up and pH down for spas. Have that around the house.
