Me again I've noticed my soils ph is a bit high. Im using ocean forest how can I lower it? I haven't used any fertilizer and just watering with ro. I think I got a bag that was hot unfortunately as some leaves are showing nute burn
I've not heard of FFOF being pH out of range high but maybe ... what is your pH reading? How are you measuring it?
For reasons that don't make total sense to me, my RO water pH is essentially the same pH of my municipal tap water ... it pH's close to 9.0. It also comes down quickly with pH down. I'd be more inclined to believe you're experiencing cal or mag issues since RO water is essentially stripped of all minerals with a ppm of 100 or less.
