Bloom City Professional Grade Ultra Pure Cal-Mag Growing Supplement Quart (32 oz)

I’ve been using the Bloom City Professional Grade Ultra Pure Cal-Mag (32 oz) for my plants, and I’m very impressed with the results. It’s made a noticeable difference in overall plant health—especially with preventing calcium and magnesium deficiencies that can show up as yellowing leaves or weak growth. The formula is clean and easy to mix, and a little goes a long way. I’ve used it with both soil and hydro setups, and it works great across the board. My plants look greener, stronger, and more vibrant since adding this to my routine. Another big plus is that it doesn’t cause buildup or clogging in my system, which I’ve had issues with in the past when using other brands. If you’re growing vegetables, houseplants, or anything that needs that extra nutrient boost, this is definitely worth trying. Reliable quality and consistent results. I'll be buying again!

This is the only general micronutrient supplement I ever buy. I first got it when my younger plants started showing signs of nutrient deficiencies outside of NPK nutrients. My plants showed signs of recovery after one watering and a few foliar applications. Some people might not need it, especially if they are growing in properly enriched soil, but I have water that's softened at a municipal level. As a result, some minerals have been removed from my water; this product helps restore those and add others that are good for all plant growth stages, from new plants to blooming plants. Use is simple. Just measure out however much I want to add to my 2-gallon can, dump it in, add water, and water my plants as usual. No worrying about presoaking anything or lots of stirring to mix in powders. (for simplicity, I use a different fertilizer bottle's cap to measure out ~8ml when filling my watering can) The bottle cap/lid and recommended measurements have changed from the previous bottle I bought. The ingredients list is the same, as well as the concentration percentages of the minerals. They also separate the use guidelines/directions differently between them. I'll only mention the amount differences. New: watering can: 1tsp (2.5-5ml)/gallon Hose end sprayer: 1tsp (5ml) approx 1:750 ratio Foliar spray: 2-4tsp (10-20ml)/gallon Old: Grow phase: 2-4ml/gallon Bloom phase: 3-5ml/gallon Sprayer instructions: 20-40ml/gallon Not sure why they changed the amounts, but it's helpful to know the ratio for using with a hose end sprayer. Overall, great value for money in my opinion.

I grow bell peppers and other types of peppers in my garden. Sometimes they need calcium and magnesium to fertilize them or they start getting the source fights on them. I decided to try this one to see if it would work. I use this and within a week, my plants perked up really well. The pepper started looking very nice and green and healthy. I’m very satisfied with this product. I would suggest this for anybody this fertilizer is good quality it’s effective and being organic makes it even better.

Great stuff.Great price would buy it again over and over again.Very good customer service is excellent.Not like athena

My tomatoes have suffered with blossom end root for years. I will admit that I am a novice gardener and I truly have no idea what I am doing. I have fertilized, time my watering, added bone meal to no avail. As a last effort, I used liquid Cal-Mag. What a difference. No more BER. My harvest has increased and I'm now tomatoes for sandwiches instead of the compost pile
