When in veg the plant is just cruising so we give a balanced type feed 1/1/1 ,10/10/10, 12/11/13 etc etc
But after about 3-4weeks plant gradually runs low on pk , so we give some bloom feed to top her up
Especially grow annnnd calmag as the calmag has more n in it so mix in relation has less pk
P for roots k for plant health ( vibrancy of the green )
I feed 1/2/2 bloom type plus add calmag
So mix is like 1/1.5/1.5 as it changed with the added n
We don’t need to know exact ratio , we just need a feel for what we pushing , if I feel they too light on occasion I will just give a feed or two of my stretch feed ( 1/1/1 and calmag to top up n )
Now with this mix I can just feed and not need top up of bloom anymore
Plus good for mums as pk nice level
Plants will be a lighter green but nice vibrant green
And we don’t worry cuz in stretch which is next we will be pushing n as plant now really growing leaf and stem plus the extra n will be stored in leafs as a safety bank for in flo as backup as we push pk again
This is the opposite to feeding grow and topping up with pk but a lot more benifits
It’s easier quicker to fix n deff than p or k def plus it’s easier to spot n def and is less damaging
Worse case n def and you lose a couple of lower fans ( no big deal ) but p or k or both defs affects all of plant and is harder to spot and then fix
One of the bonuses of the feed shedual is your always pushing something at different stages , that means if there is going to be a def , it will be the element your are not pushing so thats what you keep an eye out for ( no difficult thinking ) always in control
But in general there is no defs as you feeding plant what it wants for the job it wants to do at that particular stage with this feeding
Are plants are in veg and about to be flipped to 12/12
They have been on a slightly more pk than n in ratio , so leafs are lush green vibrant , not dark
Sure we may have lost one or two lower fans as we dial in but sure we would be cleaning them up anyway as we tidy up plant before flip
In stretch plant has a burst of growing leaf and stem so that’s what we give it , 30/30/30 plus calmag ( n in there ) pushes n in ratio
Any left over n will be stored in leafs and in stretch we don’t need to worry about pk as leafs already packed with it from veg , plus in 2-3 weeks time we be back to pushing pk for flower , so in stretch leafs are darker green
Once buds the size of your baby fingernail appear we go into flower mode
1/2/2/ or 1/3/2 ( jacks ) so now we pushing pk again
If we were to keep pushing n the plant would have to share its flowering power with growing leafs to store extra n in them , waste of energy , leafy buds less smells etc )
What ever ppm/ec you at at start of flower is your bench mark for your base feed up to start of finish
So every time you mixing more food same base ppm/ec butttttt you raise feed with pk as weeks progress
Now at about w8 on a 10w strain you will see some individual or small clusters of calyx fattening
This is the plant starting to ripen
Now the curve of growing new bud starts to tail off , you can A . Keep feeding high pk and squeeze more bud from the cola but after some time the Extra bud to electric will not be worth it ( excess foxtailing ) plus you will have extended your grow time
B . Decide to go to finish stage.
to grow bud the plant needs p and k togeather in evenish good supply , sooooo if we drop a lot of the p but still keep good k in ratio the plant is forced to finish ( 1/2/5 ) and the k will keep plant healthy to end with just p and n fade and not fried leafs from k def
So if you got extra time or that pheno or strain enjoys it you can push longer at end of flower or if you have more Sativa leaner you can force an earlier finish
So all in all
You have 3 feeds
1/3/2 for veg and base for flowering
30/30/30 for stretch
And 6/12/30 for finish ( at original base flower eec/ppm )
And a bottle of pk
And calmag
Now your growing like formula one race team
If in uk , chempak 3 4 8 and or elixir soluable fertiliser equivalent , npk ratios @SonsOfAvery
It works for every medium
Butt not coco
The idea behind it works on coco but you would have to adjust for cations ( headache ) but for everything else it works a treat
