SuperThrive Mag-Pro 2-15-4 Blossom Booster Supplement - 5 Gal

Phosphorus, Magnesium and Sulfur for Flowering Stages - 5 Gal Container

Plants moving into flowering need more phosphorus, magnesium and sulfur than a base feed may supply, and growers on low-mineral water often see gaps. This supplement adds those nutrients to a complete nutrient formula. It carries a 2-15-4 analysis with 2.0% magnesium and 1.5% sulfur.

The 5 Gal container suits growers who feed often, such as regular indoor growers and larger operations that want fewer reorders. Smaller growers who want to trial the product may prefer a smaller size.

Key Features & Benefits

• High phosphorus (15.0% P2O5) — supports nutrition during flower formation.
• Magnesium and sulfur included — 2.0% Mg and 1.5% S fill common gaps in a base feed.
• Works with a complete formula — add it to a SuperThrive Complete Nutrient Formula rather than replacing it.
• Bulk 5 Gal container — suited to frequent feeding and larger systems.

Who Should Use SuperThrive Mag-Pro

Growers who already run a complete nutrient program and want extra support at flowering. Those using reverse osmosis, rain or de-ionized water may also find it useful, since such water is low in minerals.

Frequently Asked Questions

Q: Can Mag-Pro replace my base nutrients?
A: No. It is a supplement and should be used with a SuperThrive Complete Nutrient Formula. It does not supply a full nutrient profile on its own.

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

Q: Does it contain secondary nutrients?
A: Yes. It lists 2.0% magnesium, 1.5% sulfur and 2.0% manganese. These supplement what your base feed provides.

Q: Is it useful with low-mineral water?
A: It can be. Reverse osmosis, rain and de-ionized water contain few minerals, so a supplement with magnesium and sulfur may help fill the gap. Follow the label for rates.

Q: How much should I use?
A: Rates depend on your system and feeding schedule, so follow the label directions. Start at the low end and adjust based on how your plants respond.
