nicksanswered grow question 4 years ago Im not a gardener and a noob but your soil PH was stable, your feed PH is stable, have you identified the potential cause of the spike? run off from something, pine needles seems to me if you want to tackle it you gotta account for that. I don't know much other poster would know more but #1 what are your readings what quantity of water have you flushed whats change in PH say 30min after? how much is it changing? Id wanna see incremental progress and consider PH+ water to maybe 7.5 see if it counteracts the acidity more every PH level is 10 the last i believe so it might be awhile if its super low. Be cautious of over correction be safe hows the dmg and PH today compared to yesterday.
Im a noob and using on screen keyboard spilt coffee but gl this is my thought process and what id try sending good thoughts i just killed my baby with vinegar PH of 4 run off, just posted pics she will be laid to rest this morning
