Hi skilled people, I’m growing in 70%soil/compost with John innes and 30%coco and perlite to help with drainage, my tap water is 7.8. I’ve read around so much advice on the PH of the water I give them and many different opinions, some say you must lower it to around 6 and others say it’s fine because the soil/compost will stabilise the PH itself. Should I use PH down in my water or is it fine? The plants look quite healthy .
