Amazing, that's all I can say. One of my "plants" had randomly browning leaves - I disproved all possible causes, no bugs, no pests, not over or under watering - PH was on the money. All the others got exactly the same treatment, this was the only one with this symptom. I ordered Fox Farm's Cal Mag (as I am using the Fox Farm trio plus Fox Farm soil exclusively) plucked off all the brown leaves. When the order arrived, I mixed it as per instructions, I fed that plant and all others that had yet to flower. Only 3 brown leaves the next day, but the following day, none. Not only that but all the others grew several inches overnight and show signs of flowering. This stuff is GREAT!

I recently started using Fox Farm Bush Doctor Cal-Mag Liquid, and it has quickly become an essential part of my plant care routine. This supplement, packed with calcium and magnesium, has made a remarkable difference in the health and vitality of my plants. From the very first application, I noticed my plants responding positively. The leaves became more vibrant and lush, and new growth appeared stronger and healthier. One of the things I appreciate most is how easy it is to mix and apply. The liquid blends smoothly with my usual nutrient solution, and it doesn’t cause any clogging or residue. I also love the peace of mind knowing that I’m giving my plants an extra boost of calcium and magnesium to support everything from strong cell walls to robust flowering. Whether you’re growing houseplants, vegetables, or flowering ornamentals, Fox Farm Bush Doctor Cal-Mag Liquid is a product I highly recommend. It’s reliable, effective, and a great way to keep your plants thriving all season long.
