General Hydroponics CaliMagic Supplement

Are your fast-growing plants showing signs of stress like tip burn or blossom end rot? These are classic symptoms of secondary nutrient deficiencies that can halt growth and reduce yields. When your plants are growing quickly, they can exhaust the available calcium and magnesium, leading to poor development.

General Hydroponics CaliMagic is the targeted solution, delivering a concentrated, readily available blend of calcium and magnesium to correct these issues and optimize your overall plant nutrients program. It strengthens plant structure and is essential for vigorous growth, especially in demanding crops like tomatoes, lettuce, and peppers. Use it as a supplement to your regular feeding schedule, such as with the General Hydroponics FloraGro base nutrient, to ensure your garden reaches its full potential.

FAQs

When should I start using CaliMagic?+

You can begin using CaliMagic as soon as you see signs of rapid growth. It's also beneficial to use it proactively, especially with fast-growing annuals or if you are using reverse osmosis (RO) water, which is stripped of minerals.

Can I use CaliMagic in both soil and hydroponic systems?+

Yes, CaliMagic is highly versatile and effective in all types of growing media, including soil, coco coir, and all hydroponic systems. Its formula is clean and won't clog drip emitters or pumps.

Is CaliMagic compatible with other nutrient brands?+

Absolutely. While it is designed to work seamlessly with the General Hydroponics lineup, CaliMagic can be added to any brand's base nutrient program to provide a supplemental source of calcium and magnesium. It is a valuable addition to most nutrient and supplement regimens.

What are the signs of a calcium or magnesium deficiency?+

Calcium deficiency often appears as stunted growth, curled new leaves, and blossom end rot in fruiting plants. Magnesium deficiency typically shows up as yellowing between the veins on older, lower leaves (interveinal chlorosis).

How is this different from a base nutrient like FloraGro?+

Base nutrients like General Hydroponics FloraGro provide the primary macronutrients (Nitrogen, Phosphorus, Potassium) for vegetative growth. CaliMagic is a specialized supplement that provides secondary macronutrients (Calcium and Magnesium), which are often required in higher amounts than what base nutrients provide, especially for certain plants or when using purified water.

Can I use CaliMagic as a foliar spray?+

Yes, CaliMagic can be used as a foliar spray for a rapid response to correct deficiencies. Mix approximately 1 teaspoon (5 ml) per gallon of water and spray directly onto the leaves. It's best to spray when lights are off or during low-light periods to avoid leaf burn.
