What is Professor’s Nutrients Organic Bloom and when should I use it?
It’s a certified organic, single-part base nutrient designed for flowering and fruiting stages. Start using it when flowers or buds begin to form, and continue through bloom. It’s safe for all flowering plants, including edibles, ornamentals, and fruiting crops.
What nutrients and ingredients are in Organic Bloom?
It contains nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, trace elements, amino acids, and vitamins. Derived from fish, seaweed, complex sugars, humic and fulvic acids—it’s formulated to feed both the plant and beneficial microbes.
How does Organic Bloom improve plant performance?
It supports flower development, improves flavour and aroma, enhances nutrient uptake, and boosts stress resilience. It also helps build soil structure and supports microbial activity—especially useful in organic and living-soil systems.
What’s the best way to dose and feed with Organic Bloom?
Use 2–4 mL per litre depending on your media and plant size. Start at the lower end, observe plant response, and adjust as needed. Feed according to your regular watering schedule, not as a one-off hit. Don’t stack with everything at once—keep it simple.
Is Organic Bloom compatible with different growing media?
Yes—it works in soil, coco coir, hydroponics, and inert media like rockwool and perlite. Suitable for containers, raised beds, and no-dig gardens. Just remember: smaller pots = less buffering, so be gentler with dosage.
Do I need to adjust pH when using Organic Bloom?
Usually yes. Organics can lower pH slightly. Use an organic-friendly pH adjuster to hit your target range (typically 5.8–6.5 depending on media). Hard tap water and poor pH control are common causes of nutrient lockout.
How should I mix and store Organic Bloom?
Shake the bottle well. Mix into water thoroughly—don’t leave unmixed concentrate sitting. Use mixed solution fresh; avoid storing overnight. Store the bottle sealed, away from heat and sunlight. Separation and smell are normal for organic liquids.
Can I use Organic Bloom with other nutrients or additives?
Yes, but be deliberate. It pairs well with PK boosters and beneficial microbes. Only add extra cal-mag if you’ve got a deficiency. Always mix products one at a time, monitor plant response, and avoid “stacking” at full strength.
Is Organic Bloom safe for irrigation systems or autopots?
It can be used in drip systems and autopots, but hygiene is key. Flush lines, agitate your mix, and avoid letting nutrient solution sit too long. Organics can build up if left stagnant or mismanaged.
What should I watch out for when using Organic Bloom?
Overfeeding signs include leaf tip burn, dark foliage, slowed growth, and nutrient lockout. If that happens, back off the feed and stabilise pH. Near harvest, reduce feed or switch to plain water to avoid residue in flowers or produce.
