Frequently Asked Questions (FAQ)

What is Professor’s Nutrients Organic Grow used for?

It’s a certified organic, single-part nutrient designed for the vegetative stage. Use it on herbs, vegetables, leafy greens, ornamentals, and indoor/outdoor plants to build roots, stems, and strong green growth before switching to a bloom feed.

What nutrients and ingredients are in Organic Grow?

It’s made from seaweed, fish, sugars, amino acids, humic and fulvic acids. Nutrient-wise: Nitrogen 2.07%, Phosphorus 0.107%, Potassium 1.95%, plus calcium, magnesium, sulphur, and a full suite of trace elements like iron and zinc.

What dose should I use and how often?

Start with 2 mL per 1 L of water, and only increase toward 4 mL/L if plants are thriving and hungry. Feed consistently. In hydro/coco: lighter, frequent feeding. In soil: less often but steady. Don’t hit hard and random.

What grow media and systems can I use Organic Grow in?

It’s compatible with soil, coco, rockwool, perlite, vermiculite, clay pebbles, and hydroponic setups. Works in pots, beds, drippers, and recirculating systems—just keep things clean and agitate your mix if it sits.

How do I mix and store Organic Grow properly?

Shake well before use. Mix into water thoroughly and use fresh—don’t leave solutions sitting overnight. Store sealed, out of sunlight, and away from heat. If it smells rancid or the bottle swells, don’t use it.

Do I need to adjust pH when using Organic Grow?

Usually yes. Organic nutrients often lower pH slightly. Use an organic-friendly pH up/down and aim for your target range (typically 5.8–6.5 depending on media). Wild pH swings = nutrient lockout.

Can Organic Grow cause nutrient burn?

Yes—especially if you overdose or feed too frequently. Signs include dark leaves, clawing, tip burn, or soft, weak stems. If you see these, back off, flush lightly, and stabilise pH before resuming feed.

Can I use Organic Grow with other additives?

Yes—but don’t stack everything at full strength. It pairs well with root boosters, microbes, and Grow Fast Organic. Add Cal-Mag or silica only if needed. Always mix products one at a time and monitor plant response.

When should I switch from Organic Grow to bloom nutrients?

Switch once flowering starts—usually when you see the first proper bud or flower sites. Bloom feeds support a different nutrient profile better suited for fruit and flower development.

Does Organic Grow help plants handle stress?

Yes—healthier roots, stronger structure, and better nutrient uptake help plants bounce back from heat, pests, and other stress. Just don’t expect miracles if other basics like lighting and watering are off.
