Chart displays the amount of dry fertilizer (oz.) to add to each gallon of water to make a concentrated solution. Please check your injector setting before use.

Mixing Table

Desired N Feed Rate	1:15	1:100	1:200	E.C. Value
50 ppm	0.65	4.50	9.00	0.38
100 ppm	1.35	9.00	18.00	0.76
200 ppm	2.70	18.00	36.00	1.52

Limit of Solubility = 4.5 lbs per gallon

Important Notes:
E.C. value is the best method to determine fertilizer strength. Fertilizer appearance may vary in color due to variation in raw material size and tracer dye distribution upon the particles in the bag. In solution, color will remain consistent.

For best results, use warm water to dissolve product. Jack's fertilizers are made with 100% soluble raw materials that will form a true solution. Some raw materials are slower to dissolve than others. Keep stock tank covered to reduce light and debris inputs.

What does Jack's Professional 15-5-15 CaMg LX do, and what kind of growers is the formula designed for?

Jack's Professional 15-5-15 CaMg LX is a comprehensive all-in-one water soluble fertilizer that delivers all macro and micronutrients in a single tank, making feeding simpler for both hydroponic and soil growers. The formula is especially well suited for growers using water that is naturally low in calcium and magnesium, since Jack's Professional 15-5-15 CaMg LX supplies 4% calcium and 2% magnesium alongside a full micronutrient package.

What is the guaranteed N-P-K and nutrient analysis for Jack's Professional 15-5-15 CaMg LX?

Jack's Professional 15-5-15 CaMg LX carries a 15-5-15 N-P-K ratio, with 15% total nitrogen (12% nitrate, 3% ammoniacal), 5% available phosphate, and 15% soluble potash. The formula also provides 4% calcium, 2% water soluble magnesium, and chelated micronutrients including iron (0.075%), manganese (0.0375%), zinc (0.0375%), copper (0.0075%), boron (0.015%), and molybdenum (0.0075%).

Why does Jack's Professional 15-5-15 CaMg LX use mostly nitrate nitrogen, and how does that benefit plants?

Jack's Professional 15-5-15 CaMg LX delivers 80% of its nitrogen in nitrate form, which is the nitrogen form most readily absorbed by plant roots and least likely to cause pH swings in the root zone. The remaining 20% is ammoniacal nitrogen, and the formula contains zero urea nitrogen, keeping the nutrient profile clean and predictable for both hydroponic systems and soil applications.

Can Jack's Professional 15-5-15 CaMg LX be combined with other fertilizers in the same tank?

Yes, Jack's Professional 15-5-15 CaMg LX is formulated to tank mix with other Jack's LX series formulas, giving growers the flexibility to customize nutrient programs without switching brands or systems.

How do you mix Jack's Professional 15-5-15 CaMg LX to hit a target nitrogen feed rate?

The amount of Jack's Professional 15-5-15 CaMg LX to add per gallon of water depends on your injector ratio and target nitrogen level. For example, to reach 100 ppm N at a 1:100 injector ratio, add 9.00 oz. of dry fertilizer per gallon of concentrate; at a 1:200 ratio, use 18.00 oz. per gallon. Jack's recommends using warm water to dissolve the granules fully and keeping the stock tank covered to reduce light and debris.

Is Jack's Professional 15-5-15 CaMg LX suitable for use with RO or soft water that lacks calcium and magnesium?

Jack's Professional 15-5-15 CaMg LX is an ideal choice for growers using reverse osmosis or other low-mineral water, because the formula includes 4% calcium and 2% magnesium built directly into the blend. This means growers do not need a separate Cal-Mag supplement when using Jack's Professional 15-5-15 CaMg LX as their base fertilizer.

Im a home grower

These are the absolute BEST filters ive ever used. ive been buying them for the last 15 years now. Ill never buy another brand.
This is the ONLY brand ive ever found that I can run for 4 solid years without stinking up the hood. My wife hates that. let me say... that i swap them out before they fail and turn them into air scrubbers for drying flower. to be honest the ones ive swapped out after 4 years have NEVER failed. They still make work perfectly as air scrubbers. buying the other brands made me paranoid. the other brands fail before the first run is out! my wife doesnt like it when the neighbors are phoning about the odor.

Im a home grower with 45 years experience. yeah, really. I live in a nice neighborhood with lots of people walking their dogs by my house. I grow some fantastic living soil cannabis.
Many of the strains i choose absolutely reek.

I buy the 8x40 can lites.. they fit perfectly in the top of a 5x9 gorilla tent with cam/max fans. It doesnt get any better. I look for the stinkiest strains because they taste the best. Ive probably replaced them 3 times in the last 15 years? theyve never failed. You cant go wrong here. These are the ones youve always hoped for. ive had so many fail over the years i wouldnt have believed what im saying now. im going to buy some more next run.
Id give them 10 stars if i could.

The lights are high quality

The lights are high quality. The kit contains all the hardware needed to install the light in different ways. The controller (included) is nice, but a central controller is available that can integrate numerous lights.

Great sweetener for sweeter fruit & soil health.

Love the BioNova line and this sweetner is amazing. Super concentrated and great results. Used in high flowering & fruiting plats. Also works well on things like strawberries & peppers! I bought the 1L but either seems out of stock & hopefully HydroBuilder will still carry that size.

Best PK booster on the market

Best PK booster on the market: It has everything to make things go. it contains aminos, low ballast PK 13/14 boost - and at MOST you will use is 2ml/gallon. Best product on the market. Have used in many plants: peppers, strawberries & other HIGH fruiting/flowering plants. Amazing results. If in soil, use this with the soil supermix.

BioNova is the best

I love this product in my Hydroponics garden. This would also be a great primary A/B for your garden as well. SUPER concentrated, and the highest quality inputs i've used in the hydroponics space. 10/10
