CalMag Plus Iron Liquid Plant Supplement (128 fl oz) Gallon | for All Plants & Gardens | Concentrated Calcium Magnesium Iron | Makes Up to 1,260 Gallons of Ready to Feed | Blue Planet Nutrients

I make my own plant food mixtures with liquid seaweed for my indoor and outdoor plants, as well as supplementing my AeroGarden veggies for continued growth. This gave me tasty cherry tomatoes for 200 days on my kitchen counter. Now I'm growing herbs, lettuce, and chilies with continuous growth. Very happy. A little bit goes a long way! My houseplants also grow well with these nutrients and I'm looking forward to spring to start my garden outside again. It did wonders for my veggies outdoors. They continued to grow until our first snowfall.

This stuff works. Add 5ml of Blue Planet Nutrients CalMag per gallon of water. Mix well. Check and adjust pH. I grow in soil and CalMag prevents deficiencies that manifest themselves in problems with my leaves.

I keep trying other brands but I just keep coming back to this one plants love it

I bought this because someone recommend I put calcium in my tomatoes. I didn't see any difference after using this. Pretty dissapointed :/

Great for controlling boytum end rot

I add about 2ml to a gallon of water for young plant health. Hopefully helpful, it hasn't killed them yet. The jury is still out on whether it helps with observed leaf coloration. I was primarily interested in the calcium and magnesium but the iron is likely a welcome bonus.

Worked great reviving my citrus orange tree that started to yellow from nutrient deficiency. While I use Epsom salt as a foliage and in ground supplement, it did not do enough to make my leaves green again. When I found this I was hoping the iron or calcium would help and it did! Never figured out which specific nutrient it was deficient in but def did the job.

Best supplement to stop bottom rot
