SuperThrive Mag-Pro 2-15-4 Blossom Booster - 1 Gal

Phosphorus and Magnesium Support for Flowering - 1 Gal

Plants fed with a base nutrient alone can run short on phosphorus, magnesium and sulfur when flowers begin to form. This supplement adds those nutrients on top of your complete nutrient formula. It carries a 2-15-4 analysis with 2.0% magnesium and 1.5% sulfur, and it is built to be used alongside a base feed, not in place of one.

The 1 gal jug suits regular indoor growers and small to mid-size hydroponic setups that want enough supplement to feed through a full flowering cycle without frequent reordering. It is sold individually.

Key Features & Benefits

• 2-15-4 NPK analysis — puts the emphasis on phosphorus during flowering.
• Magnesium and sulfur included — 2.0% magnesium and 1.5% sulfur supplement your base feed.
• Works with a complete nutrient formula — it adds to your existing feeding program instead of replacing it.
• Useful with low-mineral water — growers using reverse osmosis, rain or de-ionized water can add it to replace minerals the water lacks.
• 1 gal size — a practical volume for repeated feedings.

Who Should Use SuperThrive Mag-Pro

Indoor and hydroponic growers who feed a complete nutrient formula and want extra phosphorus, magnesium and sulfur during flowering. It is also a fit for growers whose source water is low in minerals.

Frequently Asked Questions

Q: Can I use Mag-Pro as my only nutrient?
A: No. It is a supplement, not a complete nutrient. Use it together with a SuperThrive Complete Nutrient Formula.

Q: What does 2-15-4 mean?
A: The three numbers are the percentages of total nitrogen (N), phosphate (P2O5) and potash (K2O). Here that is 2.0% nitrogen, 15.0% phosphate and 4.0% potassium.

Q: Is it useful if I use reverse osmosis water?
A: Yes. Water that is low in minerals can leave plants short on magnesium and sulfur. This supplement adds both to your feed solution.

Q: How much should I use?
A: Follow the application rates on the product label, which vary by hydroponic or hand-watering method and by feeding frequency. Start at the low end of the range and adjust as your plants respond.

Q: How is this different from a complete nutrient formula?
A: A complete formula supplies the full range of nutrients plants need. This supplement concentrates on phosphorus, magnesium and sulfur to add to that base program.

Q: What size does this listing cover?
A: This listing is for one 1 gal container, sold each.
