Plant fertilizer supplement
Size: 1 Pint
The fertilizer shipped quickly. I needed it fast they were delivered overnight. The product was good. Should have realized they were small bottles. That’s my only issue. But this one is only needed infrequently anyways. All good.

My plants love it
Size: 1 Pint
My plants love it. I bought this for my medical cannabis plants and it worked wonders for my cal-mag deficiency by the second watering. Would absolutely recommend and would buy again and again. For the bottle size it should last an entire season at minimum. I want to try all Fox Farms fertilizers for cannabis but that’ll have to wait until next year.

This stuff works
Size: 1 Pint
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.
