True Plant Science Cal-Mag OAC Plant Nutrient Supplement Gallon (128 oz) - Liquid Fertilizer for All Indoor & Outdoor Plants

Really helps my tomato’s to set. Some heirlooms are finicky.

The plants like the nutrients and grow fast, but the chemical has a vinegar smell that is unpleasant to the user until it is mixed with water. The mix could be a little stronger concentration. I used a separate micronutrient mix that also has calcium and magnesium, so it mixes well, but if you plan on using it as a stand-alone product, you may need to use more than the instructions call for.

Plants love it. Organic.

A must ĥave if you like growing tomatoes I am so glad I tried it it will always be a part of my secrets to having the best tomatoes try it I don't thank you will be sorry

It's not just your generic answer to problems growing cannabis.... it's the organic NITROGEN FREE calmag we all deserve for healthy photosynthesis and cell strength and over vigor. With zero nitrogen we run this exclusively at MattyBudz for years now, with nothing but excellent results. Our grow medium is coco coir so we needed a calmag that's clean and pure and it also happens to be organic. With zero deficiency in any growth due to calmag shortages at any stage for the least few years. I put all my new growers onto it and literally tell everyone who grows and needs a better calmag about it. Hands down there is no better calmag on the market. Thank you TPS Nutrient.
