Professors Nutrients Go Green (1L + 2.5L + 5L)

What is Professor’s Nutrients Go Green and what does it do?

Professor’s Nutrients Go Green is a fast-acting deficiency corrector designed to address common problems with nitrogen, calcium, magnesium, and iron. It’s often described as a “Cal-Mag plus” product, with added nitrogen and chelated minerals to help plants recover quickly when foliage turns pale, spotty, or weak.

What nutrient deficiencies does Go Green help correct?

Go Green targets nitrogen, calcium, magnesium, and iron deficiencies. These typically show up as pale or yellowing leaves, interveinal chlorosis, rust spots, weak new growth, or spreading tip burn. It’s especially useful when symptoms overlap and you’re not 100% sure which single deficiency is causing the issue.

How fast does Professor’s Nutrients Go Green work?

If a true deficiency is the cause, many growers see improved color and vigor within a few days. Existing damaged leaves usually won’t repair themselves, so judge results by healthier new growth and the problem stopping, not by expecting old leaves to look perfect again.

Can Go Green fix any nutrient problem?

No. Go Green won’t fix issues caused by pH lockout, root disease, overwatering, heat or light stress, pests, or chronic overfeeding. Always correct the underlying problem first. Once uptake is restored, Go Green can help plants recover from deficiency-related stress.

Should I use Professor’s Nutrients Go Green as a preventative or only as a fix?

You can use it both ways. Many growers run light preventative doses in coco or hydro where Ca/Mg issues are common. Otherwise, it’s best used short-term when symptoms appear, rather than automatically adding it to every feed.

What is the correct root-feeding dose for Professor’s Nutrients Go Green?

The standard rate is 2 ml per litre of nutrient solution. Because it adds to overall EC, reduce your base nutrients slightly if you’re already feeding strong. Less is often more with deficiency correctors, especially in systems prone to salt buildup.

Can I use Professor’s Nutrients Go Green as a foliar spray?

Yes. For foliar feeding, use 1 ml per litre of water and apply as a fine mist to both sides of the leaves, especially the underside. Foliar use is helpful when roots aren’t functioning well or when fast correction is needed.

When is the best time to foliar spray Go Green?

Spray when lights are off indoors, or early morning or late afternoon outdoors. Avoid strong light on wet leaves, as this can cause spotting or burn. Foliar feeding should be occasional support, not a daily habit.

Can I overuse Professor’s Nutrients Go Green?

Yes. Overuse can cause dark, clawing leaves, rising EC stress, tip burn, and nutrient lockout. If plants get darker but growth slows or tips burn, back off, check EC and pH, and let the plant stabilize before adding more.

Is Professor’s Nutrients Go Green safe in soil, coco, and hydro systems?

Yes. Go Green works in soil, coco, and hydroponic systems, including reservoirs and automated irrigation. Coco growers commonly use it due to calcium and magnesium binding issues. Just avoid stacking it on top of already aggressive feeding.

Can I mix Go Green with other nutrients or Cal-Mag products?

It’s designed to fit into most nutrient programs, but stacking it with other Cal-Mag or iron supplements is usually unnecessary and increases overfeeding risk. If you do stack, reduce doses and monitor EC and new growth carefully.

What’s the simplest way to use Professor’s Nutrients Go Green correctly?

Confirm the issue is deficiency-related, keep pH stable, use the recommended dose or slightly less, don’t stack multiple deficiency products, and judge success by healthy new growth. Go Green works best as a targeted correction tool, not a heavy everyday feed.
