Issues since 2-3 days

Issues since 2-3 days

Hi to all,

yeah my first post after almost 3 years of reading an testing. But after a long period of hydro growing I am went back to dirt for an organic grow, and I am a bit out of practice with this medium. Perhaps you could help me. Ask if something is missing. One plant is really wet now, since I've tested the run-off with her.
There are 6 strains involved:

* Kalichakra x Afgani F1 (own cross) 3 weeks old
* Kalichakra x Afgani F2 (own cross) 2 weeks old
* Sweet Purple (unknown) 3 weeks old
* Satori (Mandala) 1 week old
* Early Sativa (Earth seeds) 1 week old
* Dutch Haze (Dutch Passion) 3 weeks old

Only some of both generations of the KxA have issues.

SOIL:

What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) Composana Universal
What brand Nutrient's are you using? None yet
How much of each nutrient are you using with how much water? None yet, but I have "GH Flora 3 part", "Metrop", "Canna Terra" and "Hesi TNT" available. But would perfer organic growing that plants.

What is the pH of the "RUN-OFF"? PH=6.3, EC=1.6
How often are you testing pH/ppm/EC/TDS? Every time I am watering
What method of pH test was administered? Using Strips? pH pen? pH pen from Hanna 1 year old, calibrated today, was 7.1 PH with PH=7.01 calibration liquid, and 4.0 Ph with PH=4.01 calibration liquid
How often are you watering? 2-3 times a week for 1L and 2.5L pots, 1 time/week for the 11L pots. Only if the first 1cm substrate is really dry.
When was your last feeding and how often are you feeding? none yet
What size bulb are you using? 400W MH
How old is your bulbs? 3 months
What is the distance to the canopy? 45 cm

Is your water HARD or SOFT? light hard
What water are you using? tap
If using tap water, what is the ppm/EC/TDS of the water right out of the tap?(Only if you have a tds pen) PH=7.8, EC=0.37, I am using vinegar to adjust to PH=6.5, but I have also PH Down Grow and Bloom.

Hello,

can i get a permission to translate the entire article to German? For a German forum where we have many readers who speak no English. It would help many people ...

too much nutes, locking out K and Ca...and possibly Mg....pants that small should be fed a bit less, i give 1.8EC to my 4 foot plants....

Hello

Anyone can help me with this bubblegum? She's about 2 weeks in flower getting half dose of canna bio boost and bio flores. It's starting in low leaf parts

thanks for any advice

 

[mastervirus]

Someone will help diagnose the cause? Growing indoors, week on vegetative growth. 3 days ago spots started to appear on the leaves and slightly twisted leaves.Soil Universal for flowers and vegetables mixed with perlite, biohumus, bat guano and dolomite. More and more plants in boxing becomes ill in a similar way. Soil have good ph, water is also adjusted for the ph before watering. Ventilation is adequate, even is a power reserve. The only thing that worries me is the temperature between 34-36 degrees. But I can not do anything with this, because outside the window is 28-31 degrees. Thanks for your help.

Hello everyone...

these leaves started to show these lime green colors along with some yellowing a few days after flowering began.. trying to diagnose it it seems likely a Potassium deficiency.

Anyone recognize this particular sight?

 

[FOE20]

I'll try to help and give Joe a break....If the info is not copa with you Joe say the word and I'll remove the post...

mastervirus - Theres no problem with your seedling its the mix your using is a bit Hot for it is all...There could possibly a imbalance as well causing certain lockouts of either macro or micro causing both the Variegation(spots) and Deformations..
Some varieties need very little to nothing to get started and usually the more Sativa involved in the line the more sensitive they can be specially at seedling stages..Just water it till it mellows out and then start a feeding plan after it uses all that is in the mix to start..You say the soil has a good pH so if you use RO or pure Water the soil should stay balanced without having to pH the water as its pure enough to start...Don;t use Tap water unless you know your water supply very well..The mix looks rather rich so I'd also let it dry out a bit more before each watering to increase amount of air avail to roots between watering/feedings...hope that some help..

DaveJ...looks like she got a bad watering..Lower growth looks good to a point and the newest growth actually looks fine as well also to a point..So theres only that level that seems to be effected..Looks like it effected pH which caused some serious lockouts...But since the newest growth look ok than just don't do whatever happened last wk?..Theres a few symptoms that make it hard to diagnose as you have slight issue between the margins on lower fans as well..Then as you work up thru the plant it becomes more intense..Curling under or Clawing can be over watering or excess Nitrogen but they don't seem to have excess N to the degree to cause curling...So Im guesing the rootmass is heavy and water logged?..It could just be Ca lockout if you tried to fix it with to much CalMag?...Maybe Joe could do better helping but thats what Im seeing and hope its something that helps..gl

Im a avid trouble shooter with cannabis in my area..Not sure why but I just dig watching them get better and helping a lil life form recover..Its like a challenge even in almost every case as each can be so different...
Joe Fresh your a good person....for taking the time to help ppl...Well done and cheers to you!...

Hey hippies,

Would you be able to give a quick advice on these below pics:

Strain is: Northern Lights #5 X Haze Feminised Seeds
Nutes: Basic Lucas formula 0-8-16 per gallon (except while they were seedlings - had some deficiency as started giving nutes a bit late)
Lightting: 250w HPS + 125w CFL 2700K

Plants are in total 5 weeks old growing in a hempy 75/25 perlite/coco

Sorry about the pics they are not the best quality...

 

[StealtGrower]

Forgot to meantion they have been 3 weeks in Flowering now.

 

[avant gardener]

looks like N or maybe trace deficiency.
how's your pH and your PPM?

 

[rastaculture]

hello guys (sorry for my bad english but is not my native language)
I have a problem with 1 of my plants, other plants are very good

strain: Maxigom grass o matic
biobizz light mix
nutes:biobizz - biogrow and biobloom 0.5ml x lt from this week ( now is growing 5 weeks from seed)
lamp: 250w hps agro

 

[StealtGrower]

looks like N or maybe trace deficiency.
how's your pH and your PPM?

If you replied to me:

My pH and PPM are unknown, but I'm going with a standard Lucas Formula + pH down some drops (like 45 drops per gallon, the water here is pH 7,8).

Today I gave them 2/3 of a gallon of nutrients solution before the overfill hole started to spill excess solution out...so maybe it was a general "dry season" problem...forgot to feed enough I guess, or it is a subconscious thing to keep the ladies...ehm...thin. I am a victim of the values of a modern western society.

Sure looks like broad mite damage. Check undersides of leaves with a 100X scope to look for eggs/mites.

 

[MynameStitch]

bump!

 

[jm420]

hey stitch glad to see you around, i havnt seen you post in a bit ,but thanks to the guide i dontstop by often anymore LOL

 

[johnsilver]

most fulfilling guide ever!

 

[MynameStitch]

Thanks! bump thread... anyone who needs help you can post here if you like and I will help you out.

 

[Airnut]

No help needed ,yet, thanks to pictures and good details in the description of the individual problems.

What i did this time to figure out the issue was to combine many of the data and in there i found the problem.
It is not easy to figure out when the cause of event to wierd looking plants is due to lack of shaking the micronutrient bottle before use.
They way i found out was the data indicatet is was a combined lack of metals, iron, mangan and such, all the heavy elements had simply dropped to the bottom of the bottle and was not present in the water upon feeding.
In hydroponic this is visual within 2-3 days, and when the problem is located and fixed its stil takes a 1-2day flush and 2-3 days of wait with the new solution holding every minerals the plant needs, before the plant shows sign of getting better.

But thanks, due to this magnificient guide one more grow has been saved from a cruel certain death.
Thanks to big data, thanks to you Mynamestitch for still being so active and helpfull if needed.

Just thanks, it saved me, among many, many many many many hours of work.
