CALiMAGic 4 Litres

I have tried many other cal-mags and this one is by far the best. Don't waste your money on any other calmag, but this one and you will not be disappointed. It has readily available forms of calcium and magnesium so it works quick on any deficiencies. If you are using reverse osmosis water it's a must have!

After using easily a dozen or more calmag supplements I have to say calimagic has been the most stable, reliable and least finicky solution yet. I cannot see myself going back to any other brand as long as it remains in its current state of quality.

Don't listen to the other review that said to stop this product two weeks into flower. The plants consume tons of calcium and magnesium during flower production, and I would suggest using this if you don't want to see those week 4 deficiencies.

Super easy to use CalMag supplement. If anyone tells you that you don’t need to supplement your cannabis plants with these 2 nutrients, they’re wrong. If I had to give up all my nutrients except for 1, I would keep this 1 item

Perfect, and as described.Always consistent,always great, as is with all GH chems.Remember if your a new user, this adds some Nitrogen, so decrease your Base Nitro to avoid overfeeding,(glossy leaves)

I grow in coco coir and perlite so I am at a calcium and magnesium deficiency. This works great to counteract that. A few mls per gallon and I'm set. Plants looking great and by the gallon is a great value.

I have been using this product for years and I have to say I wont use any other except the one I make myself. Worth every oenny. You use a lot of Calmag when growing so follow the instructions.

Using this at the rate of one T per 5 gallons in reverse osmosis water. I also use the General Hydroponics Maxi series as my base nutrients, so only secondary nutrient supplementation.

Arrived quickly. Quality product. Been using it for years, but was great to have it delivered to my door, and for less than I was paying at the store👍

A must for most places who’s water is low on calcium, magnesium or zinc! Brown spots be gone! A garden must have!
