Flowering Nutrients:
1. Liquid Worm Humus - although
Canna Coco A+B has humic+fulvic acids added I like to add more as it allows me to reach an ec of 2.0 with many plants.
2. Liquid Silicon
3. Seaweed Extract
4. Base Nutrient - I prefer
Canna Coco A+B, works so well and I have zero problems using it so I see no reason to switch unless they produce an organic BioCanna version of their coco nutes.
5. Roots Excellurator - I use this for first 3 weeks to get the plants to fill out the larger flowering pots with roots as I usually transplant plants when I put them into flower.
6. AN Hammerhead - I used to use either
Atami or Canna PK13-14 but after a tip from joeshmoe I tried AN Hammerhead and find it gives a bit more resin just as joe said it would so big props to joe for that tip. Also, it's pretty cheap compared to other AN products and often cheaper than Canna PK.
7. Canna Boost - it's so expensive but it works
8. Molasses - for sugars, I am going to experiment with other sugar sources such as white sugar (sucrose), golden syrup etc. Products like Vitrasol, Carboload and ATA Organics Flava are just molasses really and I find a cheap jar of unsulphured blackstrap from the healthfood store works just as well and it's certified organic.
9. Rooster Liquid Tomato Booster - for Potassium, I use Rooster brand liquid chicken manure as an organic source of K bu they have ceased production so I will have to find an alternative product or make my own liquid from dry chicken manure.
10. Liquid Bat Guano - for Phosphorous. I have used No Mercy and Guanokalong brands with success, there are others such as Budswel and I guess they work just as well.
My nute regime is rather complex but let me give you a rough breakdown for a typical 14 week flowering run of the type of sativas mostly grow:
Week 1 - Liquid worm humus, liquid silicon, seaweed extract, roots excel,
canna coco a+b, Canna Boost, ec 1.5 ph 6
Week 2 - Liquid worm humus, liquid silicon, seaweed extract, roots excel,
canna coco a+b, Canna Boost, ec 1.6 ph 6
Week 3 - Liquid worm humus, liquid silicon, seaweed extract, roots excel,
canna coco a+b, Canna Boost, ec 1.7 ph 6
Week 4 - Liquid worm humus, liquid silicon, seaweed extract,
canna coco a+b, Canna Boost, AN Hammerhead, Molasses, ec 1.7 ph 6
Week 5 - Liquid worm humus, liquid silicon, seaweed extract,
canna coco a+b, Canna Boost, AN Hammerhead, Molasses, ec 1.8 ph 6
Week 6 - Liquid worm humus, liquid silicon, seaweed extract,
canna coco a+b, Canna Boost, AN Hammerhead, Molasses, ec 1.8 ph 6
Week 7 - Liquid worm humus, liquid silicon, seaweed extract,
canna coco a+b, Canna Boost, AN Hammerhead, Molasses, ec 1.9 ph 6
Week 8 - Liquid worm humus, liquid silicon, seaweed extract,
canna coco a+b, Canna Boost, AN Hammerhead, Molasses, ec 1.9 ph 6
Week 9 - Liquid worm humus, liquid silicon, seaweed extract, Liquid Chicken manure, Liquid Bat Guano, Canna Boost, AN Hammerhead, Molasses, ec 1.9 ph 6
Week 10 - Liquid worm humus, liquid silicon, Liquid Chicken manure, Liquid Bat Guano, Canna Boost, AN Hammerhead, Molasses, ec 2.0 ph 6
Week 11 - Liquid worm humus, Liquid Chicken manure, Liquid Bat Guano, AN Hammerhead, Molasses, ec 2.0 ph 6
Week 12 - Liquid worm humus, Molasses, ec 0.8 ph 6
Week 13 - Molasses, ec 0.6 ph 6
Week 14 - water ec 0 ph 6
That is the nute regime I used to produce 0.9w per gram with 8 plants in 1.5 litre pots of coco under a 250W HPS in a 85cm wide 45cm deep wardrobe and I have produced 45g per plant with my El Yucateca and Highland Oaxacan Gold cuts in 1.5 litre pots so I reckon it works very well, the end product is very clean as i cut out nutrient for the last 3 weeks just giving water and molasses with a lil bit of humates in week 12 to help with the uptake of the remaining nutrients held in the coco medium.
I cut out all Nitrogen after week 8, just giving P and K in the form of AN Hammerhead which gives great yield and resin production and liquid chicken manure which improves yield and bat guano which improves taste, cutting out the N really increases the density of the flowers and the plants end up with beautiful autumn colours on their leaves by the end of week 11 when I stop feeding. The 3 week flush means I lose a load of lower leaves and the others turn yellow, but I feel this is how plants should look by the time they are done - withered and yellowed foliage but glistening fat juicy buds.
