My conclusion on organic, water soluble, nutrients
This example is Kelp Extract but same logic (not dosage) applies to Soy meal (N), Alfalfa (P), Nettle/Blackstrap (K), field horsetail (Si)
(Kelp isn't about NPK and all of these also include the needed Minerals and other stuff)
When using organic Grow/Bloom like BioBizz, you benefit from Alfalfa, Low NP Nettle or Blackstrap, field horsetail and Kelp.
You can combine all of them if you want to do everything by yourself but do your research. Kelp is like always useful.
Using these makes pricy booster products completely obsolete.
Note:
- Some heavy feeders can take additional, directly absorbable, mineral PK. But it's much less than in Coco/Hydro
- Water based stays 1 week in soil (higher- or over- dosage stays longer)
- Top dressing meal / powder can stay longer, average 2 weeks. Rely on manufacturer/research information
Species:
- Ecklonia maxima (better)
- Ascophyllum nodosum (double the mentioned dosage)
Disclaimer:
- Dosage obviously does not apply to kelp meal or powder, but you get the general idea
- Please keep in mind that some products have higher NPK, but the pure kelp isn't about NPK
- Your nutrients may already include the same base ingredients
PH: 4.6
Dosage:
- Less than 7 Liter Soil: 1 ml/Liter
- Less than 15 Liter Soil: 2 ml/Liter
- Less than 25 Liter Soil: 3 ml/Liter
- No more than 5 ml/Liter
Use once per week and stop 2 weeks before harvest (when buds mostly reached their final potential)
Heavy drinkers/feeders benefit from half dosage but twice per week.
Do not combine with other boosters. Apply other boosters on different days and at least 2 days after the kelp.
There is no benefit in using less or more of the extract. no need to experiment. Stick to manufacturer dosages if unknown!
