ENVY CalMag+ (4-0-0) Professional Grade Calcium, Magnesium and Iron Liquid Plant Food Supplement for Hydroponics & Soil (Quart)

i have to grow my vegetables in large grow bags. The last items we had in them pretty much drained the calcium and magnesium from the dirt. So this year, wanting to grow tomatoes, we had to add Cal Mag. I purchased this product to do so. The instructions are simple, however, I do think they overdue. Because we killed two tomato plants almost immediately. Once I lowered the amount of cal-mag I added to the water, my tomato plants perked up and are doing wonderfully. My advice would be to add it every 3 or 4 days, rather than with every watering.

Bottle arrived open. Box was clean and dry. Upon opening the bottle, I noticed the seal had been pealed back and it appeared some product was missing (don't have a reference as to where the fill line should be). Gives me the feeling I was jipped. That's enough to keep me from buying this again.Product itself seems to do its job.

I have been gardening for years and one issue that has come up almost every season is blossom rot. That is where the blossom end of your tomatoes turns from a light brown to a black. I have found that a good share of the time it is due to a deficiency in Calcium and Magnesium. The CalMag Product provides those needed minerals and is easily absorbed by the plant. I use very little once the plant starts to produce fruit, but that is enough to keep the tomatoes plump and juicy.

I've never been a fan of most CalMag supplements; a bit too little or too much and the whole mix goes south. Envy's CalMag has yet to cause me any issues, and from the color and yield of my ladies, I can tell they truly love it as well.

This turns out to be half the gallon cap to the gallon of water. So simple and it brought my tomatoes back to health in just a few doses. The first few were getting dry and nasty on the bottoms of those tomatoes. The next ones to the very end were nice and healthy juicy. This really works well

I like the 4.0.0 more than the 2.0.0 My plants love this stuff. I use the A/B and Trigger as well. Evny are every bit as good as AN, FF, GH, and anything else for that matter.

Should have purchased bigger bottle :) Lowers PH slightly but my tap water is too high so it's fine. I generally use less than recommended amount, but I do this with most nutes.

Better than botanicare calmag plus.
