Had a pH disaster this week, had been using Britax filtered water but used 2L tap water for the first time and didn't pH it until the next day when I noticed some issues in my leaves. Turns out the tap water was pH 8.5 so quickly added some pH'd 5 water to counteract (about 0.5L)
Started LST but she's quite short and bushy so also took a leaf to expose budsites.
