I'm using soil , 50% fox farms original planting mix with bat guano and earth worm castings , and a potting soil
I'm using advanced 3 part grow micro bloom , feeding 1/2 strength every other watering ,waterings include molasses and magnifical.
I'm in week 3 of flowering , I'm thinking about using pk13 14 ,but when? Strains are 9 weeks of flower.
I haven't used it before but here's what I found on the Canna website: "The nutrients potassium and phosphate are indispensable for plants during their flowering period. PK 13/14 is a venerable potassium - phosphate mixture. PK 13/14 dissolves well and is therefore easily absorbable.
Shake the bottle well before use
Add PK 13/14 once to a full nutrition tank
Dosage: 0.2 fl oz/Gal (15 ml/10L)
Use for approximately one week only"
