FLOWER A+B · Coco bloom base
Fill the frame.
FLOWER is the bloom half of a two-part coco base — Part A and Part B shifted toward phosphorus and potassium to put weight on the sites your veg built.
Australian-made · 26 years in the US · N-P-K A 6.8–0–6.2 · B 1.6–8.4–11.8
Why it matters
Bloom wants different food.
The plant’s diet changes at the flip — less nitrogen, far more phosphorus and potassium. FLOWER is tuned for exactly that.
Bloom-tuned P-K
Shifted toward phosphorus and potassium for bud.
Lower nitrogen
Backs off N so the plant commits to flower.
Coco-specific
Balanced for coco through the bloom weeks.
What’s in the bottle
Tuned for bloom.
Here’s what’s actually in each part — read straight off the current bottles — and what it does through the flower phase.
Part A
Potassium nitrate Mineral salt
Potassium plus nitrate nitrogen, dialled back so the plant commits to flower.
Calcium nitrate Mineral salt
Calcium plus nitrate nitrogen for cell wall strength and transport.
Ammonium nitrate Mineral salt
Ammoniacal plus nitrate nitrogen, two nitrogen forms in one salt.
Iron EDDHA EDDHA-chelated iron
The most pH-stable iron chelate available — keeps iron plant-available through bloom.
Vitamin B1 Thiamine
A touch of thiamine alongside the base minerals.
Part B
Monopotassium phosphate MKP
Phosphate plus potassium in one salt — loads the two nutrients that fill flower sites.
Magnesium sulfate Epsom salt
Magnesium plus sulfur — chlorophyll and enzyme function through bloom.
Chelated micronutrients Cu · Fe · Mn · Zn EDTA/DTPA
Copper EDTA, Iron DTPA, Manganese EDTA and Zinc EDTA — four chelated trace elements declared on the label.
Boric acid + sodium molybdate Boron · molybdenum
Two more mineral salts on the label — boron and molybdenum in trace amounts.
Humic acid Leonardite humic
Keeps minerals available so the plant takes them up efficiently. May increase micronutrient uptake.
Why a dedicated bloom base
All-purpose vs. FLOWER.
One base for everything
✗
Same feed for veg and bloom.
✗
Too much nitrogen deep into flower.
✗
Generic, not coco-tuned.
✗
Sites never fully fill.
FLOWER (bloom)
✓
Purpose-built for the flower phase.
✓
Lower N so the plant commits to bud.
✓
Balanced for coco specifically.
✓
P-K to fill every site.
A little goes a long way
