Cronk Nutrients CalMag 2-0-0 - Calcium, Magnesium and Iron Plant Fertilizer – Compatible with Soil, Soilless and Hydroponic Garden – Correct Common Deficiencies for Indoor & Outdoor Plants, 1L

I used this last year for my tomatoes and peppers. I usually use it once when I transplant then once when they start getting their first fruit. Diluted according to the package. Depending on my soil conditions, I'll water with it every 3 weeks. It went very well! Every tomato was perfectly healthy the entire season.Favorite part about this product is the cute packaging (everyone loves the little bug guy) and how it's the perfect size for a small gardening kit! I have a plot at a community garden so I can't lug around a huge jug of the stuff nor store something big in my tiny apartment. This is the perfect solution if you can't carry around something huge. It's still great value too as long as you dilute it as directed.

Works great

I’m a new grower and came across Cronk through YouTube. The price seemed fair and the product looked good on paper so I figured why not give it a shot. I purchased the base three nutrients from Cronk but found myself needing to supplement additional calmag on a few of my plants due to genetic differences and thankfully Cronk offered just what I needed. I prefer to stay in the same ecosystem because logic dictates that the folks that made the stuff tend to know how to best pair them and at what ratios. Needless to say the additional calmag from Cronk has been working perfectly. It’s gentle on my plants all the while providing what they’re in need of. I look forwards to trying out the other offerings in their line of nutrients. I’ve no reason to recommend anyone other than Cronk nutrients. Their products…work…as…advertised.

What More can I say about their products, all make my plants productive!

The girls love it

For my first grow I followed the Novice 3-part Nutrient System feeding schedule and had such a huge success that I ordered more for my next grow. This stuff is MAGIC juice!

Great nutrients

Works great
