late flower ppm count recommendations please.....

[generalgrievous]

i've always mixed nutes by keeping track of tsp/tbsp per gl..... start light and increase....sort of instinctive guess work....i'm a long time backyard grower....

now i have a small perpetual indoors and keeping track of two gardens in different stages of life.....well it got confusing....

as of yesterday i started using a ppm meter.... only to realize, what i thought was a massive dose of nutes is 930 ppm....and in mid 5th. week i'm seeing signs of multiple deficiency's....i'm not stressing it cuz bud growth has obviously not slowed....

i hand water in coco...at the moment i'm feeding with EJ bloom, liquid karma, aqua shield, cal-mag+, in r/o....

i need some thoughts on nute strength.... in veg, early flower, late flower, seedling, clone....

does this thing read everything i put in that water...? i'm an old soil grower going coco.... any help is greatly appreciated

1550 it is for tonight

1550ppm.....

I run Maxibloom exclusively for veg and flower. Since Maxibloom is very similar to the Lucas ratio, and since the Lucas ratio calls for the same ppm throughout flower, I simply bump my ppms from 3/4 strength in veg to full strength in flower and keep it their until I flush at the end of flower. (Full strength Maxibloom is roughly 1 tsp/gal and full strength ppms with my tap water is 1250, 950 nutes and 300 water)
PS, I too grow in coco

EDIT
What defs are you getting?

 

[Kcar]

It also depends on your conversion factor of your TDS meter. At .5, 2EC=1000ppm and
at .7, 2EC=1400

I think the upper limit is between 2.5 and 2.85 EC which is 1250 to 1425ppm at .5
and 1750 to 2000 ppm at .7

Much above those numbers I believe is a waste and could burn your plants.

 

[Guest 18340]

So true man, that .5, .7 conversion always confused me. My numbers are with a .5 pen.

 

[Dr Dog]

This is what I try to follow

Week 1 500 ppm of veg nutes 500 ppm of flower nutes

Week 2 1000 ppm flower nutes

Week 3 1100 ppm flower nutes with bloom boosters starting

Week 4 1300 ppm flower nutes

Week 5 1700 ppm flower nutes

Week 6 1900 to 2000 ppm

Week 7 500 ppm with finishing additives

week 8 0 ppm nutes and tap water


This is my sched, works well, I do have to adjust it now and then depending on strains and temps, but I try to stick to that

Hey General, you could try using the accelerated formula of Cal-Mag @ 10ml/Gal to stop the deficiency. Coco likes to hold onto magnesium so that might help.

My ppm through flowering is:

Week 1 - 800 ppm
Week 2 - 900-1000 ppm
Week 3 - 1000-1100 ppm
Week 4 - 1100-1300 ppm
Week 5 - 1000-1100 ppm
Week 6 - 900-1000 ppm
Week 7 - 800 ppm
Week 8 - Flush

I'm using the AN organic line at ~1000ppm plus I add guano tea to get my ppm in range.

Peace

thanks for your feeding schedules guys.....

i flip through my garden saver book and the deficiency's to me, look like phosphorus, potassium, and magnesium... i have some pics in my cam from last night.... i'll post 'em tonight.

i'm so close to the end here and bud growth is stacking up, no signs of slowing....can we crash and burn this close to the end....???

i try to be a stress free grower so i'll just up the munchies and see what happens...

that is practically my ppm schedule exactly except I give a bloom boost early to get conversion started stronger.

I have often thought about it, that is why I give a transitional nute regiment the first week. I also find that it gets all the stretchiness out by the time week 2 has started

I do not think there is a wrong way, I just like to see the preemie buds before I start giving them bud food

 

[generalgrievous]

made the nute mix.....

1550 ppm... this includes 5 ml/gl cal-mag+, 5 ml/gl aqua shield, and 10 ml/gl. liquid karma..... topped to 1550ppm with EJ bloom..

from here i adjusted to ph5.5... that took the ppm to 1850.... do the amounts you guys have listed as weekly totals, include ph adjusting..?

my tap is 250ppm.... 5ml/gl cal-mag+ in r/o is also 250ppm....can i bag the r/o and cal-mag+for tap water in that case......

in doing so i would also bag the chelating agent EDTA... which i recently decided i absolutely must do....

heres a couple pics of the necrosis, curling, yelowing between the veins... calyx's are opening up everywhere dumping out tangled, thick masses of hair, so i won't complain....

bud porn and garden pics located ...HERE....

hopefully she keeps doing what she's doing and the extra food takes care of whatever is giong on with her leaves....

 

[Zealious]

just read about the edta in skunk. Yea that junk must go.

My tap is like 160 but i still use cal mag.. i get better results.. Plants seem to like that source of cal mag better...

U should maybe use molases for mag. and Im no expert but I belive u got mostly a P def. which can be affected by ca mag.. u might have ca mag lock out if ur using ca mag with 250ppm tap..

I would maybe flush and use molases for mag.

 

[generalgrievous]

Cal-mag+ and r/o.... or straight tap.

Cal-mag+ and r/o.... or straight tap.

u might have ca mag lock out if ur using ca mag with 250ppm tap..

I use cal-mag+,250 ppm apparently.. With r/o,0-10 ppm.

I would like to replace this combo with tap at 250 ppm.... And forget the cal- mag entirely..... Would also like to stop with the ph adjusting.

Not sure if I'm that brave yet....

 

[milehimedi]

what's the conversion factor all about on TDS meters (.5, .7)? I just got a TDS meter and don't know.

 

[generalgrievous]

not sure how the math works.... tried to figure it out but didn't get anywhere...

pretty sure the 3 bong rips didn't help....

some how it's the multiplier in converting EC to the PPM reading.... mine is an oakton but i can't locate this conversion factor on the box or the web site.....i'm feeding in the 1900's now and she seems to be responding well....

do you guy's feed these numbers straight through.... daily...? any plain watering or slight flushing during flowering...?

these def. didn't start till i started screwing around...

i got a little bit of 'the claw'...

i changed to the EJ bloom for a no N bloom feed...but for some reason decided to cut everything across the board after a moderate flushing...

several says later is when the tips started to dry, than shortly after that the weird stuff kicked in.

i think she wasn't getting enough food as she's a decent size plant in a small pot...i'm not too concerned with the leaves as long as he keeps stacking up with bud growth....

all of a sudden nutes move very, very slow.... through the root ball.... i mean slow...any thoughts on that....

 

[TalkingMonkey]

over 900 ppm doesn't sound like a shortage of nutes., try raising your ph. 5.5 sounds a little low...maybe 5.8 or 5.9 so more potassium and mag will be available. 1900 ppm is working? sounds like alot of nutes , I am not in coco though.

P.S. my plants see 1100-1200 ppm max @ 5.9-6.0 ph in flower (they are very happy) Good luck Gen.G

Why is it that a gal of my 60ppm tap water mixed with 16ml GH bloom (like later flower after dropping nitrogen and trying to get them to hulk up).. only 450ppm? that means 16cc/ml of bloom is only giving me 390ppm.

I feel like i've been flushing light down the drain, 4 plants around a 600w and it's like all of my branches have maintained a smallish stance to them even with that much light, in a vertical setup too!

Please, someone/anyone tell me how much ppm I want of flowering nutrients only - I have done rez's koolbloom bump, done with those (i'm day 50, want another week of heavy bloom fert before I flush for a week or more)

EC/TDS/PPM/CF = the same thing...just different equations to arrive at the same info

A Bluelab Truncheon give you 4 readings......

PPM on the 500 scale (.5) , PPM on the 700 scale (.7) , EC and CF (EC and CF are the same really)

SO.......1.0 EC on the BL is either 500 PPM or 700 PPM.....depends ont eh nutes you are using. For US made nutes, use the 700 scale. For nutes made in Canada or Europe, use the 500 scale.

So if I mix 2 buckets of nutes, one Fox Farm and one GH and stick my Truncheon in there, say it reads 1.0 EC in both buckets. My PPM for my FF nutes would be 700 and the PPM of the GH bucket would be 500 PPM. Even tho they are both 1.0 EC.

If the entire world went by EC, there would be alot less confusion of PPM/TDS/PPM scales....etc.

Bluelab Truncheon is, IMO, the best nute meter you can buy.


Back to the topic at hand.......I start off Week 1 bloom at 1.5 EC (about 1000 PPM) and peak at about 1.8 EC (about 1300 PPM) at Week 5....then back down to 1000 by Week 7. Then a solid flush for 7 days.

Works for me.

 

[VAtransplant]

So feeding my plants 9ml of bloom only (as per rez formula) after the kool bloom powder slams..is underfeeding? I know that's the "failsafe" amount, and I have increased it all the way up to 0/16 of bloom. 16ml of bloom only being 400some ppm though to a gal? seems weird.

 

[krunchbubble]

your ppm's dont mater at all unless there burning. you have lockout, i suspect its from using cal-mag, most likely p lockout. with coco i would experience this alot, until i stopped using cal mag in flowering. if i do use it, its at 1/2 strength, once every so often. in my experience, cal mag is good till the second week of flowering, unless you have a calmag whore like kush....

my last run of the pure kush, i measured the ppm's in my res the last day before flush and it was 2800....
