Had a calcium toxicity from trying out a couple Nectar For The Gods supplements I got in a free sample kit from them. I looked then up and their whole lineup is calcium based so that makes sense. I flushed the pots out really well and then I brewed a compost tea with earthworm castings, green compost, humus, seaweed extract, humic acid, fulvic acid, kelp powder, some malted barley, NFTG Zeus Juice, Primordial Solutions Sea Green, a little Hyshield, some Europonic Nitrozyme, Europonic Fossil Fuel, and then some blackstrap molasses and brown sugar. I brewed it for 40 hours and then I added 1 cup per gallon of water and fed all my plants with it. They all perked right up. They seemed to love it.
