SERIOUS DAMAGE? 7th WEEK DAY 48 FLOWER DIYING LEAVES

[Xganggreen]

AMNESIA HAZE
7th week of flowering ( DAY 48 )
fluence leds 70cm from the top of the plant at 98% power
temp is 29•C/84.2•F by day - 23•C/73.4•F by night
tap Water is EC 0.2 (tds500 is 100-ECx700 is 140)with temp 18.5 •C /65.3•F
watering is:
EC 0.6 (ppm500TDS is 300)(ppmECx700 is 420)
after nuts and BLOOM A/B water is EC 1.2 =(ppmTDS500 is 600)
(ppmECx700 is 840)
PH 6.5 (comes from veg 5.7/5.8 FLOWER 6/6.1/6.2...etc)
50% soil 50% coco
humity is below 60%
CO2 is 1500ppm today
Extraction runs 15mins per 1 hour lowering CO2 to 470ppm
2 fans (ventilation not a issue)

LAST EC MEASSURE/FLOOD from irrigation water full with A/B+ nuts EC 1.2 in 2 taller and 2 shorter plants result 1.3/1.4/1.6/1.6

Could be lack of potassium due a calcium to high block?

closer pictures

At the 3rd week of flowering , at day 21 the CO2 was started. Some internidal strech / stunt happenned, the buds doesnt seems to build up normally

Cant believie you got to this stage with 50/50 mix/coir. How did you treat that?

Here a picture of some of the buds/ tops

Actually this room got a twin, but others are fine and been fine with this ratios since a year when some friends we change from sodium to LED.

the third "brother" of this room, meaning all conditions , same clones...etc had a tech issue so the CO2 was triggered a week after and looks exceptional.


What you mean with "how did you treat that?" May I can give you more data

I mean feeding and watering schedule...? Not talking about playing good vibes or kissing the plants. I always thought that mixture of coco coir and potting mix do not work unless that potting mix is Promix hpcc. Do you have some pics of rippen plants before chop in this medium? Look like you know what you are doing so just curious if this is even possible...

So watering schedule is kinda simple.every other day, at this stage is kind of 450/500ml on smartpot. Then alternating estimulants, plain water ph with rising the EC to 0.6 (from the 0.2 EC that comes from the tap) and estimulants + A B . Measuring that day how is the EC (full estimulants, AB food + rise the plain water to 0.6 EC = 1.2 ) which got to 1.6 at the highest point When meassuring the drain from irrrigation.

First time with LED and thought playing in the safe side with EC due that "lack of cal/mag when with LEDs", so in flowering week 5th 6th 7th when PH is 6.5 and the CO2 is over 1200ppm ...the absorvtion of potassium is at its finest PH 6.5. Actually the plants stunted/increased the inter nodal distance in week 4th early 5th...which is a sign of potassium blocking sometimes (as I just learned) . The buds dont get build up being amnesia haze, sative, and watching it grow many times...also other friend have a brother room but he triggered the CO2 a week after (tech probs) and his field is doing ok.

we been talking to friends with LEDs but none really know, tons of not trustable info....after sit down and disclose every nutrient in every bootle of my advance products that I used the last weeks (b52, rhino, cannazym, connosiour A B, big bud, bud candy..etc) and checking the calcium on it seems like is not need to rise the EC so much and never with the A B at least (even with estimulantes you still not playing calcium low) but still thinking something more is going on.

Like may need something to break the particles still in the pot?....some plants roots seems like death, plant looks ok but never the pot gets weight

...also sodium being a gas light and adding CO2 in the room increse a red spectrum which being a gas acts like a sodium effect.....

plants with smart pot being feed more and CO2 rising room temp to 29 celsius (also got them to sleep in 23 celsius which also provoques stunt cause is + 5 celsius difference between day/night )

With CO2 , ph 6.5 and EC in 1.2 seems like boosted a fatal cocktail when in Flowerin weeks 6th and 7th the plant was ready to party but the dealer provide downers ?

What do you think?

I am interested in other poeple, may more familiar, with LED COCOsoir CO2 ?

 

[Xganggreen]

Some pictures the days of the inter nodal/stunt/strech happened and I thought something is wrong

 

[Xganggreen]

You can see in the picture above some curling in the leaves but also some pistils turning brown longer than the half of the pistil. Also yellow tip burns but some one with brown

 

[Xganggreen]

Also that "frostiness' is weird, they dont look like tricomas...

Uh, you are running far bigger action than I thought, so my points may not be valid but I try my best. First of all I think you shot for wrong pH. 6,5 is way too high in mix of coco and soilless, I think you gonna be golden 5,9-6,1. You definitely HAVE to pH every irrigation, but that you probably already know. Another thing is volume of your water, I consider it innsufficient half litre every other day, I have to water my 3L coco container with 2L every day fyi but you gonna probably have some automatic watering system which I am not familiar with. I am just old school growing under the street lights hand watering. So you said you measured runoff at 1,6 EC and what volume of sample did you take measurements? Another thing is that peat decays like a crazy under fertilization program, once you add things like cannazym or similar, you can very easy throw things out of ballance. You are not organics so this thing is abslutely unnecesarry. CO my brother I completely dunno, do not you need to run temps over 30C in sealed environment with PPFD higher than 1000 to make it works?

Thank you very much Bukvičák.

I am using smart pot 7'5 L of 50%coco 50% soil. When I measured the run off was watering it with 750ml . Anything over 500ml and my pots run off water, so I come out to 500ml the right amount to run off just a lil bit and no overwater.

( I got a humity meter in a pot and when out of the bag the coco/soil gives me 10% humity, and I always keep it over like 50% like a way to let the soil dry and be sure the roots got enough oxygen/not overwater)

What you mean not being organic / cannazym not being neccessary? Can you extend in this please?

with CO2 : yes is being said that you need to run it over 30 ºC and over 1000ppm but you will find out that works , and actually the charts point you, to start in 700ppm . Also over 30º C you get the room too humid, too keep it at 29ºC / 29.5ºC mean you got it below 60 % RH humity to avoid mold.

I thought about the PH levels also as l increase them a long the growing stages. Where can I get more info about the excess of PH you mention?

this PH chart is being used for long ago in this coco soil I am using here with good results. Truth is some friends and I change some parameters in our rooms at the same time and not one by one cause we are new to LEDs and we were confident coming with experience from sodium. But some friends are having good results....

It is not study about weed, but you can find a lot of similarities. On page 6 there are explanations about nutrient balance and pH in soilless. I never dealt with CO2 since I consider it too expensive to run for my needs so can not be helpful in this. Enzymes are like support for microbes, enzymes releases nutrients for plant as well as food for microbes from dead organic matter, not only roots but also peat and coco so the whole medium. You put enzymes and it can result with excessive N or K for plants. I do not use it since almost all enzymes are derived from sugars and I do not completely understand what it makes in medium, I like to it keep it as simple as it can be. Are you and your buddies have same cuts in same medium?

I think you can find your pH range for coco almost everywhere.

thank you very much for the pdf. Gonna study it now.

yes some of us got twin rooms. Same cuts same medium
Which means if you got other two people growing in the same way as you and if you have a clone box you can give clones ones to each others when needed and also ask other to prun ealier or a later to fit in your schedule. (actually the ideal is have a tent for veg in 3 L two levels which will be the half of the size of the flowering room) (transplanting from 3L to 7.5L takes 2 weeks of extra growing inside flowering room , thats true , but you still saving 2 weeks in in veg plus the veg gets 1 or two week more in every run )and a room for flowering only, ....so if you are 3 people you can harvest a lil more times by year; from 4.5 to 6.5 harvest every one

 

[Bukvičák]

Beggining of this is also interesting

 

[Wanderer1]

Some pictures the days of the inter nodal/stunt/strech happened and I thought something is wrong

IMHO looks like excess N in these pics,ask me how I know . Possibility that this continued to "toxicity", which itself causes leaf issues, causing nutrient lockout? Have you done any "flush" to attempt a "fresh" start and try to rebalance, clear excess, nutrients? Just throwing this against the wall. Have a great day. TC

I am afraid I am small fish helping this big operation my friend...

I think you can find your pH range for coco almost everywhere.

The issue is we dont use coco, is blonde turba mixed with coco so is more like soil with a lot of coco...is 50% turba and 50% soil ...so for the first two week in veg plants dont got any nutrients as the soil got the nuts.

How would you treat it PH/EC wise ?


pd: actually I think something is changed in the sustrate we buy usually, but cant say it yet. Cause if our charts been working well for long time...this weird issue in only two of us , just cause chanching to LED ...not sure but I dont think is only the LED chart....but I am very new to LED CO2.
Not blaming other is clear that we did wrong our maths about nutes +food+ec+ph = dissaster. But we took our time to play safe with the info we had about LED + co2 +soilcoco
