Oligo Spectrum GHE – Essential Micronutrients & pH Buffer

Oligo Spectrum by GHE (now Terra Aquatica) is the comprehensive nutritional insurance your crop needs to reach its full potential. This concentrated additive provides a complete range of chelated micronutrients combined with organic pH buffers, ensuring that your plants not only have access to all the trace elements they need but can also absorb them efficiently regardless of the growing medium.

Is your crop suffering from silent nutritional chaos?

You know the feeling: you have your NPK base nutrients perfectly measured, your lights are on point, but suddenly, the leaves start turning yellow, showing rust spots, or growth simply stalls. It's the nightmare of every grower: hidden deficiencies. You start guessing—is it Iron? Calcium? Magnesium? Or maybe a pH fluctuation locking everything out?

This uncertainty creates unnecessary stress and wastes valuable time. Trying to diagnose and fix specific micro-deficiencies one by one is like playing whack-a-mole; while you fix one, another appears. Meanwhile, your plants are stressed, their metabolism slows down, and you are losing grams off your final harvest with every passing day of inaction.

Oligo Spectrum is the master key that brings order to this chaos. It delivers a perfectly balanced cocktail of essential trace elements in chelated form, meaning they are immediately available to the plant. Plus, its pH stabilizers ensure the environment remains optimal for absorption. It’s the all-in-one solution to keep your plants green, vigorous, and stress-free.

How your plants change with a complete micronutrient profile

Once you introduce Oligo Spectrum into your routine, the visual change is almost immediate. That pale, lackluster green turns into a lush, vibrant, deep green—a sign of peak chlorophyll production. The stems thicken, and the plant's immune system strengthens, allowing it to focus entirely on producing flowers rather than fighting for survival.

In systems like hydroponics, where the water has no natural buffer, this product is a game-changer. It acts as a bridge, ensuring that even if you are using cannabis fertilizers that might be lacking in trace elements, your girls get a full-spectrum diet.

What does Oligo Spectrum GHE provide?

This bottle is packed with the "building blocks" that base fertilizers often overlook or contain in insufficient quantities:

• Chelated Iron: Essential for photosynthesis and preventing chlorosis.
• Molybdenum & Cobalt: Vital for nitrogen fixation and beneficial bacteria.
• Zinc & Copper: Key for enzyme production and healthy root tips.
• Organic pH Buffers: Helps stabilize the nutrient solution, preventing dangerous swings.
• Boron: Crucial for sugar transport and cell wall structure.

How to use Oligo Spectrum for maximum results

Whether you are running advanced Hydroponic and Aeroponic Systems or growing in traditional soil, usage is simple:

1. Hydroponics & Coco: Add 5 ml per liter of nutrient solution. It works alongside your base nutrients.
2. Soil: Use 3 ml per liter of water. It’s perfect for revitalizing reused soil.
3. Foliar Spray: For a quick fix of deficiencies, mix 2 ml per liter of water and spray the leaves (always with lights off or at sunset).
4. Maintenance: Use it regularly throughout the vegetative and early flowering stages to prevent issues before they start.

Advantages and benefits of chelated nutrition

• Total Absorption: The chelated formula means the plant doesn't have to work hard to eat; the nutrients are "pre-digested."
• pH Stability: Reduces the constant need to adjust pH with acids, keeping the root zone happier.
• Aquaponics Safe: It is one of the few products safe for fish, proving its purity and quality.
• Yield Booster: A plant with no deficiencies produces heavier, resinous, and more aromatic flowers.

Frequently Asked Questions

Can I use it with other brands of fertilizer?

Yes, absolutely. While it's designed by GHE (Terra Aquatica), it acts as a supplement and works perfectly with any nutrient brand to cover micro-deficiencies.

Is it organic?

Oligo Spectrum contains certified organic elements and is compliant with organic farming regulations in Europe, making it a clean choice for conscious growers.

When should I stop using it?

You can use it throughout the vegetative stage and the first weeks of flowering. Once you start the final flush, you should stop using it along with all other nutrients.

Personal Experience of Pevgrow’s CEO (Alan)

I've always said that micronutrients are the unsung heroes of a massive harvest. I keep a bottle of Oligo Spectrum in my cabinet specifically for two situations: when I'm experimenting with new hydroponic setups and need to guarantee pH stability, and when I see a mother plant looking a bit tired after taking cuttings.

The reaction speed is what I like most. You spray it foliarly on a plant that's starting to yellow between the veins, and within 24 to 48 hours, you see the color returning. It’s like a vitamin shot that wakes the plant up. If you are growing in RO (Reverse Osmosis) water, this stuff is basically mandatory if you don't want to run into trouble later on.
