Thistle says: "You can combine CropSalt with Emerald Harvest, but it can be risky and usually isn't needed. If the plants show hunger, then go for it. Use 6 ml max per part as an example.
Note: Use 2.0 ml of Emerald Harvest only for the first week. Do not use CropSalt until the plant starts developing its second pair of leaves. After the first week, Emerald Harvest is not needed, or you can use the existing calculator rate of 0.5 ml." 🧚💨
