Professors Nutrients A & B (1L / 5L / 10L)

What is Professor Nutrients A & B and how is it used?

Professor Nutrients A & B is a two-part base nutrient designed to support plant growth and flowering from start to finish. It works across all plant types and grow styles—indoor, outdoor, hydro, soil, and coco. It's a complete, all-in-one nutrient solution for consistent results.

Why does Professor Nutrients A & B come in two parts?

Part A and Part B must be used together. Keeping key nutrients separate prevents unwanted chemical reactions and keeps the formula stable. Always mix Part A into water first, stir well, then add Part B. Never mix concentrates directly together—they’ll clump and reduce effectiveness.

How do I use Professor Nutrients A & B in hydro, coco, soil, or outdoors?

Professor A & B suits all grow media. In hydro/coco, feed more regularly and monitor EC and pH closely. In soil or outdoors, use lighter doses and feed less often. For seedlings and clones, start at reduced strength and increase as they grow.

How much Professor Nutrients A & B should I use and how often?

Use the feed chart as a starting point, then adjust based on your plant's growth stage, medium, and EC readings. In hydro and coco, feeding is more frequent. In soil, less is more. Always monitor runoff and plant response for best results.

Do I need to adjust pH and EC when using Professor Nutrients A & B?

Yes. In hydro and coco, aim for pH around 5.5–6.2; in soil, 6.0–7.0 is common. Always check EC or PPM to avoid overfeeding or underfeeding. These tools help prevent lockout and nutrient issues.

Can I combine Professor Nutrients A & B with other products?

Yes. It works well with root boosters, bloom enhancers, silica, and Cal-Mag—just be cautious not to overstack. Always follow mixing order: silica first (if using), then A, then B. Avoid mixing with other base nutrients to prevent overfeeding.

Is Professor Nutrients A & B safe for edible or medicinal plants?

Yes. When used as directed, it’s suitable for edible and medicinal crops. If using as a foliar spray, dilute heavily and spot test first, though foliar feeding isn’t generally recommended with base nutrients.

Why is my nutrient solution cloudy or showing residue?

This often comes from incorrect mixing—like adding Part B before Part A or mixing concentrates together. Sediment in bottles can also form if stored cold. Warm the bottle gently and shake to dissolve.

How should I store Professor Nutrients A & B, and what’s the shelf life?

Store in a cool, dark place with lids sealed tight. If kept properly, the shelf life is long. Crystals or mild sediment can occur over time—shake well and check that it dissolves before use.

Where can I find the Professor Nutrients A & B feeding chart?

You’ll find the latest feed chart on the product page or manufacturer’s website. Use it as a baseline and adjust for your grow style and plant needs.
