Oh that clears things up! If tea won't work, can you get your hands on something like GeoFlora Veg? It's a top-dress and works well for SIPs (from what I hear).I’m sorry, scratch everything I said & let me start over. I saw the same spotting on a few of her sister’s leaves today and I’m certain they weren’t there yesterday. Then I remembered they’re both in the store bought soil I’m using to compare to my (The Rev’s) soil mix, so I looked at the bag & it says no amending necessary until the roots fill the soil, which they have clearly done. They recommend top dressing with their compost mix which I don’t have, but I can brew some compost tea. Interestingly enough, recipe is from the Rev’s book I got my soil. Whaddaya think? @Gee64 ?
