I usually don’t go higher than 2.0 EC for peppers. This will give you a point of reference for future batches too. It’s good to check the EC/ppm strength when mixing a new batch.With my tap water, it comes out close enough, but you might need to adjust yours. Check the pH and adjust if necessary to around 6.0 +/.Measure 2 grams of Calcium Nitrate and put in the container.Add a little more water to the container, filling up to about 2/3 full.Measure 1 gram of Epsom Salt (Magnesium Sulfate) and put in the container.Measure 2 grams of Masterblend and put in the container.I use tap water, but use whatever you feel is best. Fill the container halfway with water.If you’re mixing for a larger container, like a 5-gallon bucket, for example, adjust the amounts up to as needed. If you’re mixing for seedlings I would adjust this by half or quarter. If you want to mix a gallon, the steps are as follows. When I do need to calibrate, it’s only off by about. It works with a 500-gram calibration weight, which I also purchased, but I rarely ever need to use it. It’s very inexpensive, I’ve used the same scales for years with no problems. I have one that I found on Amazon, AWS brand that weighs up to 600 grams. You’ll need some accurate gram scales to measure the ingredients. I’ve seen a lot of misinformation online/YouTube showing the Calcium Nitrate mixed second, but this is wrong. This is to prevent a nutrient lockout from occurring. You want to always mix the Calcium Nitrate last. The MasterBlend and Epsom Salt could be combined together in the same jug if needed, but I find it easier to mix one thing at a time. Also, the premixed bags will be inconsistent anyway. The reason is they need to be mixed in the proper order. You absolutely DON’T want the kind that has all three components mixed together in one bag. You can source out the materials separately, but I’ve found them on Amazon fairly cheap, all in one package. For greens and lettuce, I’ll use 1.6/.8 ratios. I might bump the ratios up to 2.4/1.2 for mature plants.
For peppers, I use 2.0 grams/gallon of MasterBlend, 1 gram/gallon Epsom Salt, and 2.0 grams/gallon Calcium Nitrate. Basically, use half the amount of Epsom Salt that you would use for the MasterBlend and Calcium Nitrate amounts respectively. Generally, the ratios should be 2 parts MasterBlend, 1 part Epsom Salt, and 2 parts Calcium Nitrate. It is best combined with Magnesium Sulfate (Epsom Salt) and Calcium Nitrate. MasterBlend, also known as 4-18-38 tomato fertilizer is a very inexpensive and effective hydroponic plant food.

This article describes how to properly mix MasterBlend and the equipment needed. This is at no extra cost to you and helps support my website and YouTube efforts. Some plants may benefit from up to 25% more magnesium sulfate.As an Amazon Associate, I earn commissions from qualifying purchases made through links in this post. NOTE: Masterblend and Magnesium Sulfate must be completely dissolved prior to adding Calcium Nitrate to prevent nutrient lockout.ĭilute to 3/4 strength for seedlings. Nutrient solution is now ready for use.Add 16 grams of Calcium Nitrate (15.5-0-0) into the water and mix until completely dissolved.Add 8 grams of Magnesium Sulfate into the water and mix until completely dissolved.Add 16 grams Masterblend Lettuce Formula (8-15-36) into the water and mix until completely dissolved.Place 25 litres of warm water into a container.It is 100% water soluble so it won’t clog sprayers and when used with magnesium sulfate and calcium nitrate (sold separately), it creates a super charged solution that contains all the macro and micro nutrients your greens need to thrive. Ideal for use in any hydroponic system and even in soil.
Masterblend’s 8-15-36 lettuce formula is specifically formulated to maximize yield with all types of lettuce and other greens and it’s now available in Canada exclusively from Gecko Grow.
