leaf problem

[THC123]

high

I got a problem with my frisian , i consulted the leaf faq in the sticky's above , but still i am not sure

Here are few pics

the 2 pics above are the 2 branches i am talking about.

here other shoots they look normal

At first i thought N def but it's only 2 pairs of leaves on each branch , the new ones look ok and the ones beneath also.


Then i was thinking overfert , but 98 % of the plant is fine.

µ

Now there is one thing that happened to those branches. They are the branches of the big branch attached to the stem that broke a while back , i put it back in place . All the rest is fine but i am afraid it will spread .

So anyone got any ideas?

Thx

Needs more N and probably P and K as well. There is no signs of overfeeding that I can see in your pix. That's a big plant in the sun that is hungry and you need to feed it more.

 

[DiscoBiscuit]

What HP said. 1st pic looks light a slight K def, (burns on the margins)

 

[THC123]

Thx for the tips guys.

i also made a short movie , in the second part u can see the leaf problem.

i don't speak english natively so excuse me for my accent

maybe this will make it even easier to reach a conclusion

after last nights rain i took new pics as i saw other leaves beginning to have troubles.

I already fed the plants liquid with bio bizz bloom 1ml/l(instead of 2-5)

Should i give them a higher dose?

And now that you see the new pics , are you sure its p and or k DEF and not burn or sumthing

this is same leaf as 3 days ago she has gone from yellow to purplish/red on the margins

She is in a 500 liter hole with on the bottom 200 l of flowering mix , so to me it seems strange that with such a big amount of good ameneded soil she can have def.

But it is the first time i ever seen this purple yellow shit so any extra advice is appreciated , ùaybe the firsian is an extremely hungry girl and the top 300 l is growing mix thus containing less p and k

The rain will have taken even more from the leaves - reverse foliar feeding -, the plant in the film is huge, it needs lots of P and K now, maybe a touch of N till flowers set, its a lovely plant.

 

[Mr. Greengenes]

You're right. The chance that a cannabis plant growing in a $50 hole has a deficiency is none. It looks quite wet where you are. Does the soil drain well? It also looks like you have some winters there, and probably already have decent soil fertility and low PH?

 

[THC123]

Well it's not the driest place on earth , i got the same climate as germany

The soil drains wel it has40% cocos/perlite in it and the universal potting soil itself is also very airy the ph of the soil is 6.8-7 just like plagron royalty mix

Now i must say this plant is in a hole with used soil , no new bough soil mixed in. just amended. The problem started 3 weeks ago

I added 1 liter of compost/soil amender per 10 liters of soil and a bit of wormcastings.

The top 100 liter is just used soil
then the next 100 liters is weak vegging mix
then 100 liters of strong vegging mix
then 200 liters of flowering mix.

This plant has been in this hole since may , i fed her some dry amendments once and some fishmix.

lately i have been adding bio bizz bloom once per week @ 1 ml per liter instead of 2-5

I just want to be sure before i give them extra p and k. I'll do it with dry amendments but with that there is no way back so thats why i want to be sure

Phosphorus is a component of certain enzymes and proteins, adenosine triphosphate (ATP), ribonucleic acids (RNA), deoxyribonucleic acids (DNA) and phytin. ATP is involved in various energy transfer reactions, and RNA and DNA are components of genetic information.



Figure 11 is severe phosphorus (P) deficiency during flowering. Fan leaves are dark green or red/purple, and may turn yellow. Leaves may curl under, go brown and die. Small-formed buds are another main symptom.

Phosphorus deficiencies exhibit slow growing, weak and stunted plants with dark green or purple pigmentation in older leaves and stems.

Some deficiency during flowering is normal, but too much shouldn't be tolerated. Red petioles and stems are a normal, genetic characteristic for many varieties, plus it can also be a co-symptom of N, K, and Mg-deficiencies, so red stems are not a foolproof sign of P-deficiency. Too much P can lead to iron deficiency.

Purpling: accumulation of anthocyanin pigments; causes an overall dark green color with a purple, red, or blue tint, and is the common sign of phosphate deficiency. Some plant species and varieties respond to phosphate deficiency by yellowing instead of purpling. Purpling is natural to some healthy ornamentals.

ok you guys where right here i found more detailed info , so tomorrow i will dress the top layer with npk 6-4-11 + bone meal 2 spoons

thx for your input guys and gals

 

[DiscoBiscuit]

Although the margins looked like a K def in the first two pics, it now looks like something else. I rarely hit the nail on the head the first time.

I don't think it's over watering as leaves don't curl upward with too much water. The color reminds me of a molybdenum def.

Too much of the plant looks healthy to be a macro nute def, IMO. This is another reason I think it's a Mo def. According to one of the nute charts in the infirmary, Mo is best absorbed in soil at 7.0 pH. If it is Mo, I wouldn't worry too much unless it spreads to more parts of the plant.

 

[THC123]

k thx 4 your input , i have this molybydium in biobizz bio heaven

 

[THC123]

hey i also read the chart , and well yeah in the veyr beginning it DOES look like N def untill leaves start acting weird and it also had the purple coloring

 

[THC123]

Well i top dressed the soil 12 days ago with npk 6-4-11 and bone meal and have been feeding her bio bizz bloom 2-6-3(npk) and bio heaven(for the micro nutrients) twice a week

But still the problem keeps getting worse.

I have been growing organically for years this way with the same recipe and never ever had problems.

I am becoming pretty convinced it must be an imbalance in the soil.

From now on i will only work with fresh soil , i will never try to save money and use the same soil for years(what i did this year , i used 3 year old soil)

 

[THC123]

Well we are again 14 days further

so the npk pellets are working now since it rained 2 times and i gave water.

I also have been feeding them bio bizz bloom(macro nutes) and topmax and bio heaven(micro nutes)

Normally i don't ever mix solids and liquids , but i was following the guide's theory.

So i gave them liquids so they got extra nutes immediately and the npk pellets on top soil cuz they will keep working in the long run or on days when it has rained a lot and i cannot give liquids then the npk pellets will do the job.

But i must say normally there is never need for liquid nutes. i mean the plant has a friggin 500 liter hole , i got plants in 50 liter pots that don't show any def and that where only fed ONCE (a handful of npk)

All plants are going fine in exactly the same recipe without extra nutes.

So i will again try to give as much details followed by ugly pics

-----------------------
The probs began when preflowering started first the leave has less tension and start to droop and become pale , then they droop even further and start becoming yellow/purple

In the end they wrinkle and turn brown and dry.

the difference between the frisian dew is that the soil is old amended soil , the other plants have new or half new half old soil.

Point being that the plant never had a prob since preflowring started.

is supposed to be P and K def but i mean again 500 liters of soil!!!!!!!! plus she has been fed twice a week micro and macro plus the top soil is dressed.

ph is about 6.8 like all my plants

the buds seem to be forming fine has been flowering since 10 days.

I just hope the entire plant won't turn yellow or purple it looks soo fucked up


here are the ugly ass pics

this is the same branch as in the last reply so you can see how it has progressed

this is how it begins. notice the leaf tension they droop and compare it to the tension of the normal leaves beneath

especially the main top shoots have this not the lower growth

normal lookin leaves

left side plant

right side i couldn't get her in one picture cuz she is so wide


So anyone got any ideaés now you seen the further development and after taking into account the info??


if you need extra info jsut ask


i have a feeling she will still yield nice but i can't stand those leaf problems

but i am really clueless never seen this type of problem and nothing i do seems to fix it , it keeps getting worse

 

[ibjamming]

I looks isolated to those plants/branches... Tear them out if you're worried...could be a disease?

Otherwise...the plants look marvelous...

 

[Core]

i would just stop feeding it...if they are in such a big hole you'll know they will have food to there disposal. just don't overcare them...i think they should be fine...even more now you fed them
coz in that large pic i see more then a few tip burns don't forget leaves also can go yellow from to much....

Thats just it though, a small container holds in nutes, a large open earth absorbs the nutes downwards. There is an article in maximum yield magazine that talks about how most of these bloom boosters are overkill for containers which will grow fine with 1-1-1 NPK but needed outdoors where the nutrients aren't contained in a small container which is why all those bloom boosters have so much damn P, common belief will tell you a container pot needs more nutes but its the opposite

mad respect on those monsters in the video

 

[mrred]

i would give it a light flowering tea, with certain chemicals it could kill the microherd and you have to feed it regularly, and i would stay away from bonee meal, heard it attacts bugs, maybe bubble some wormcastings,kelps and molasses.

 

[mrred]

oh and indonesian bat guano to that if you dont think its getting enough p
