how often should i feed/water my plants in coco?

[joeparak]

@joeparak

sent me a PM hes sourced calcium nitrate so where going to rebuild his mix using it instead of the "calmag" liquid that was cost prohibitive

I thought I go ahead and post it here for anyone else whom had interest

for veg
full strength per gallon
base 1 gram
bloom 1 gram
Ca-N 1.5 grams
Epsom 1 gram

bloom
full strength per gallon
base 0.5 grams
bloom 1.5 grams
Ca-N 1.5 grams
Epsom 0.75 grams

the only down side to this formula (and the other) is the iron

unfortunately neither the base or the bloom have enough iron in them
if your area is known for having iron in the source water then you might be ok

otherwise it would be nice to find a way to up the iron and maybe the P if there where more available options

i made this mix and it sounds like a pretty solid mix too and i guess i should use it every other watering with plain water right? my sorce water has got some good iron levels like 2% too since its mostly local mineral water all im worried about is the N in my npk nutes and CaN leading to a n tox tho should i worry about that at all?

the amounts of N are within good ratios for both veg and bloom

adding in the bloom nute which is high in K and low in N helps offset the high N content in the base nute and the calcium nitrate

that's a good amount of iron in your source water so youll be fine with the iron no problems

the N and K and calcium and magnesium amounts in the mix are perfect ratios

the only other potential for improving your mix would be to find another water soluble fertilizer that has P as its largest number
the current bloom mix could use some more P
in your PM you mention 10-52-10 that's available to you
provided its water soluble

give me the % info listed on the bottle for the calcium and magnesium amounts and whatever else it lists
and see if it works for you

im going to call/name the 10-52-10 fertilizer "high P" to make it easier

if the big P fertilizer contains micro nutrients like manganese and zinc you can mix a prefect bloom mix like this
per gallon/full strength
1.5 grams bloom 3-11-38
1.5 grams calcium nitrate 16%N 19%Ca
0.75 grams high P fert 10-52-10
1 gram Epsom salt 9.5% Mg 12% Su

again that's provided the 10-52-10 fertilizer has micros and your source water has the iron

are you sure the source water has that iron? or guessing

I'm enjoying seeing this blend come together. I hope Joe sticks around long enough to share his results when it comes to that time.

I have a question @im4satori if you don't mind, I have always used canna coco which is a two part bottle used from veg to bloom, also I use the PK13/14 around week 5 of flower. The A+B combined have a NPK of 5-4-3
First I'm wondering if I can lower the A+B and add the PK earlier, like week 2 of flower, possibly using half dose of PK13/14 until later in flower?
I'm also wondering since I can get 1.5kg of potassium sulphate from a local store cheap if I can drop the PK dosage and add some more K to make a higher K ratio to P. Say around mid flower onward.
From some other nutrient charts which contain more parts I see a P used more than K early in flower and then less P but a lot more K later on. This is the case for the RAW nutrient line. So would that be of benefit?
What is considered a good overall NPK for bloom?

tbh my source water is local well water purified with some chloride and iron in it

im not so sure but since its local wells water purified and all i guess it has some iron and chloride too so the first mix without the High P,cool name tho lol,is good to go right?
the high p npk powder got the micro nutes of 0.05% iron 0.02 magnesium and 0.02% zinc

it doesn't list manganese?

unfortunately the high P sounds light on micro nutes so im not sure its going to mesh

using it would require the reduction or elimination of the base nute which is required in order to get you micros

so for now id have to refer you back to the previous recommended formula that doesn't include the high P

to make it work youd either need another high P fertilizer thay has more of the micros or youd need a high P fertilizer that contains little to no N

one more thing
im concerned about your water filtration system and the chloride used to filter it

I would use water for your plants that is pre-filtration water if the filtering system uses chloride

you don't want that chloride in your mix itll be too much

Sorry both the high P and my bloom got some 0.02% manganese,not free magnesium

 

[im4satori]

ya
your still better off without it

the previous formula looks better

the high P just doesn't have enough micros to make up for lowering the base

ive got your info saved in my computer so if you come across any other fert options it wont take but a minute to check it

so go window shopping and take a picture of the label of each product you find so it shows the % info clearly listed

don't buy anything just see whats available and check back in so you don't throw your money away

don't bother with anything that's time released or slow release or organic

not sure what you mean buy 5-4-3 combined

each bottle should have its own npk numbers

potassium sulphate is awesome but its very very powerful with 50+% K
so to use it you will need a very good scale or need to mix large batches because a small amount makes a big difference

 

[im4satori]

after spending some time looking at it

if the high P is inexpensive you could mix it like this

which looks exactly perfect for bloom except the noted low iron

base 0.5 grams
bloom 1.5 grams
Ca-N 1.5 grams
high P 0.25 grams
Epsom 0.75 grams

this provides close to a 2:1:3 ratio between npk and a 4:2:1 ratio K:Ca:Mg

heres how it shows when its converted

N 104ppm good
P 44ppm good
K 150ppm good
Ca 75ppm good
Mg 37ppm good
Su 52ppm good
Iron 0.5ppm extremely low (ideally 1.5 to 2.0ppm)
Mn 0.27 a little low
Zn 0.17 good
B 0.16 good
Mo 0.01 good
Cu 0.06 good

Yeah I had to google the NPK which told be the combined ratios , but I will go in my groom when I get home from work and check the individual bottles. Or download the data sheets. Will PM you when I have the info.

@joeparak

you sent me a message asking about soil vs hydro
im going to link you to my journals

1 is hydro with more plants sog style and the other is my first soil grow with only a few large plants so you can compare the differences
