Im currently planning a grow and ive been researching everything possible that will help me on my way to beautiful plants!
However the only thing i havent been able to find is in depth knowledge about is what are the best nutrients to use and what cycles to use them in throught the different stages of plant growth. So;
1# what is the best brand of nutrients out there? (must be available in the UK)
2# What type of nutrients should i use throughout the diff stages of plant growth
3# What nutrient ratio's should i use during the 3 stages of plant growth?(Seedling/vegetative/flowering)
Ideally if anyone could give me a rough starters nutrient list or any links to one that would be great.
Cheers guys
1# Canna
2# Use the feed chart as guidance if your just beggining. you will ALMOST ALWAYS want to use LESS than what the chart calls for. Everyone develops there own feed schedule. What works for one person may not be good for others. Most importantly, will you be using soil or hydro or coco or soilless mix? Depending on your method you will develop a working feeding formula, in other words the frequency of plain watering vs. feeding the plants etc. When growing in soil it will retain nutrients for prolonged periods of time, and will not respond immediately to feeding vs. hydro that will respond almost instantly and needs to be given a steady supply of nutrients because there is nothing to "hold" in hte nutrients. Some people believe in the 'feast and famine' theory, others lightly fertilize each time water is delivered to the plant. I find personally LESS IS ALMOST ALWAYS MORE, which you will find in experience, and to use the MINIMUM amount of base nutrients (npk+micros) as possible, and give a good flush at the end with clearex and you will get the most finished highest quality fruits.
3# If you want to know ratios i'd have to know your strain and method and container size, temps and humidity, co2 yes/no? etc.. but i can give you some general ideas:
You will need the following Canna nutrients products:
(they make 3 different versions for the veg A+B & flower A+B, soil/coco/hyrdo i beileve)
1. Veg A+B
2. Flower A+B
3. Rhizotonic
4. Cannazym
5. PK 13/14
6. Canna Boost
Will you be using a R/O machine? What is your water like? Depending on water conditions i would possibly reccomend getting a calmag supplement like Magical or Calmax or whatever. Canna is formulated for soft water but if your ppms are extremely low you will need to supplement the calcium and magnesium that is absent. On the flip side, if your ppms are extremely high and you are in a hardwater area i would reccomend getting a bottle of Clearex or even House & Garden drip clean to keep salts under control. One last thing, the Canna Boost is EXPENSIVE $100US/L but is GOOOOOD shit. It makes the plants ooze resin. its like pure sugar cane in the finest form the plants almost respond instantly to it. Good stuff.
Anyway,
Seedling
10mL/gallon Rhizotonic
How much Veg A+B you use TOTALLY depends on what system you are using.
Veg
5mL/gallon Rhizotonic
Again, depends -?- veg A+B
40mL/gallon cannazym
Flower
5mL/gallon Rhizo
Again, depends -?- FLOWER A+B
40mL/gallon cannazym
10mL/gallon cannaboost
There are different opinions on when and how much to use the PK 13/14. Be careful it is VERY powerful. Use once or twice when the buds begin to foxtail around the stem and are just beggining to seem like one large nug as oppose to a bunch of little small ones, just after growth stagnates and full flowering has begun. Lower your base ppms and DO NOT use larger doses or for more than a week. I forget exactly the dosage but i would say 2/3 strength of the reccomended dosage on the feeding chart would be MORE Than sufficient.
I have 2 last bits of advice. Alot of friends have recently switched to House and Garden Roots Excelurator as opposed to the Rhizotonic. I am wary because i donot know what exactly is in the rhizotonic and if they include any of the other things you need with the rhizotonic. Like humic and fulvic acids, any of the micro nutes etc. Dunno? I do know the Roots Excelurator produces SIGNIFICANTLY bigger rootballs than the Rhizo, but i still wonder ill lose any other important nutrients by switching? Something to look into if you have the time? Last bit of advice. If you are growing an strain advertised as an "8 week" finisher, let it go a full 9 weeks and begin flushing with clearex at the beggining or middle of week 8 giving it ATLEAST 10-14 days flush. You want your fruits to mature and fully finish. I used to think nuting them up full strength till the end would give me the ultimate big ass nugs. What ended up happening was i would burn my plants, and they would never finish and get that nice ripe look and flavor. By tapering the nutrient input slowly towards the end, and finally giving a thorough flush it really lets the plants fully finish get hard and resin covered and colorful and stinky and tasty and all the good shit. Good luck! Hope this helped a little. Post back with more info and we can maybe get into specifics.
