I just have the PH down, just be careful with it - it's potent stuff. I use about 4.5ml in a 5litre bottle of water to get mine down from 7.8 to 5.9 (dont forget i'm in coco - yours needs to be 6.4 ..unless you have a soil ph issue) (or if i'm lazy and just doing my 2 litre watering can it's about 14 drops for me)
I occasionally mess up and put too much in and then have to amend by pouring in more (7.8ph) water - but that's not ideal as if i have carefully measured out nutes in my 5 litre bottle and i go too far down, i essentially have to dilute the mix with plain water.
I've considered getting PH up - but usually just go back to thinking "i'll be more careful"
So after my ramble lol - it's your call! but definitely need PH down ^_^
BTW.. the soil looks nice! it has a nice clean airy feel to it when you mix it doesn't it!
