DEFICIENCY of some sort....ADVICE?


#1

Hi guys n gals. So I’ve got some almost finished autos and a few photo type which have recently made the change to flower. Out of all 8…only 1 is being testy. I havent done anything differently to the Durban poision that I have to the others…but she just seems not well. Yellowing leaves with brown patches in the center…pictures attached. I’ll even throw some pics of the healthy girls in.
ANY ADVICE OR HELP IS APPRECATED.
Thanks in advance.




AND NOW THE REST OF THE BEAUTIFUL LADIES.

Hi…sorry for not answering sooner but I’ve sort of feel hopeless. I’ve been reading on that strange parasite that attacks the roots and those pics look just like the roots I pulled up. I have never heard of that parasite before"Root Knot Nematodes". Is it a common thing? Anyways maybe that’s not the problem and I can save the rest. The strain is suppose to be “church”…feminized seeds from UK. I believe it came from a place called Attitide?? They are outside in beds…same beds I used last year with no prob. My friend mixed the soil…same as last year…dont know exactly what he puts in it but I know it is all good. My ph of water after mixing in fish fertilizer and sometimes thrive is 6.7 and the ph of soil after feeding is 6.7. My plants are still in veg I believe. They are not drying out very fast which concerns me but the plants roots that I pulled up were not slimy and did not smell. They just had those tumor looking growths on them. I’ve been told those could be a number of things from nutrient build up to something to do with good bacteria. I will send some more pics. The one with white on leaf is how it starts
Looks like a paint brush stroke of white. Then it turns yellow and the whole leaf is burnt. Leaves curling up. It all happens fast. The last pic is my next almost “gone” plant


#6

Forgot to mention…i am in Mojave desert where it has been very hot…it was staying at 110 during day…80 at night. Today a high is in the 90s. I have shade cloth up. The fact that they stay as wet as they so in this heat concerns me. Day 3 since I watered last and moisture meter at 6inches down reads WET. Last year I had to water every day


#7

I am new here, so I don’t know anything really, but I read this…maybe it is a start? At certain acidity levels, certain elements can’t be absorbed by the marijuana plant’s roots. If the pH level is too low, for example, your marijuana plant won’t take in magnesium very well. Therefore, even if you’re feeding plenty of magnesium to your plants, they still will exhibit signs of a magnesium deficiency.

A magnesium deficiency includes yellowing of leaves and even whitening, but the veins will still be green colored. Simply supplying your marijuana plant with more magnesium will not suffice, however, since the pH level is actually the root of the cause. The key, in this case, is to balance the pH level (or, in the case of a magnesium deficiency, raise the pH level) until your plant can take in nutrients


#8

The last picture looks a little like mine when it had a phosphorous deficiency…so maybe your roots are locked up and not drinking

I WATER THEM TWICE A WEEK *IF NO RAIN EACH PLANT GETS 1.5-3L AND A SMALL BIT OF MONSTER BLOOM(0-70-50FOLLOWED BY ANOTHER 1.5L . IF RAIN I USE THE FINGER TEST (STICK FINGER IN 1" AND JUDGE BY WHAT I FEEL) THEY ONLY GET THE MONSTER BLOOM ONCE A WEEK. WHILE THEY WERE GROWING I WAS GIVING THEM 7 DROPS PER G OF CACTUS NUTES. 2-7-7. STOPPED AS SOON AS SIGNS OF FLOWER.

THE ONLY THING I CAN THINK OF IS WHEN I TRANSPLANTED HER YESTERDAY THERE WAS A LARGE AIR POCKET BUILT UP IN THE ROCKS AND SAND. THE PLANT SEEMED LIKE SHE WAS GETTING A LITTLE ROOT BOUND, BUT NOW SHE HAS LOTS OF ROOM TO STRETCH OUT. I STOPPED USING NUTES ON HER ALL TOGETHER. THE OTHER FEW LOOK TERRIFIC SO I FIGURE A WEEK OR 2 OF WATER CAN’T HURT ANYTHING… ANYTHING I MAY HAVE OVERLOOKED OR FORGOTTEN I’LL UPDATE ASAP. THANKS LOADS TO THE COMMUNITY!


#10

WOW…that does look similar. The bottoms of the plant started to yellow then fall off. And the tops or what’s left are layering very closely together. I didn’t see anything to say bugs. But I may have missed something microscopic. Thanks for the info m8.


#11

@Tr33 I was thinking the same according to leaf symptom charts…except look at what I’m feeding her…theres no way she can be deficient with thoae types of numbers, maybe poisoning?? Does anyone know if the symptoms are similar?


#12

@Mischief, if her roots are refusing/ can’t take in/locked out the nutes you give her…I just don’t know enough to be of help to you. @nug-bug @Covertgrower @Jmesser80 @Countryboyjvd1971 anyone? can you guys help


#13

Only thing that jumped out to me was

Is the pro mix veg soiless? If so needs to be 5.8 @Mischief


#14

I’m doing some research. Anyone ever hear of nitrogen-fixing Nodules? They generally are associated with legumes and such, but I have found some questioning regarding MJ.- 420 mag- “Been growing in organic super soil for many years and a few years ago my roots changed. The plants are perfectly happy and it causes no ill effects. All my strains roots now are covered in nodules and all I can really find is that nitrogen fixing bacteria causes root nodules but I was under the impression that the bacteria only effect legumes”.

Any hints on what causes it?


Look familiar?
Anyway, I was thinking maybe you can re-root your plants as a last ditch effort if all else fails?
I’m still researching and if I can find anything, I’ll be back


#15

Ok, sorry for the many replies, but the purpose of the nitrogen-fixing nodules is that they house bacteria that can take nitrogen from the air and feed it to the plant. Maybe(ok, might be a reach but)maybe somehow, your plants were able to utilize bacteria already in the soil in an attempt to get the nitrogen it needs but it either is ODing on nitrogen or has suffocated it? Sorry if this sounds strange, but I am trying to help.


#16

Here is an article regarding cannabis and the nitrogen fixing nodules. It is over my head, and i am hoping some of the budding stars here can interpret it for us.http://thcdesign.com/probiotic-farming-soil-inoculation/


#17

Geesh, I walk away to make dinner and bake bread, and I miss all the action. Haha. No specialist here, but I read into this very same thing, and that’s what it appears to be. Although I didn’t read up on it on cannabis roots. I think that just means you have very healthy soil bacteria. (Which is a good thing)


#18

You in promix ph should be in 5.8-6 range your ph is to high promix is a soilless mix and should be treated more like hydro regarding ph
6.5 is for soil @Tr33


#19

SORRY ALL I SWORE I PRESNT REPLY LASTNIGHT. MY APOLOGIES!!

@Nug-bug I don’t believe it’s soiless. And after combining some compost and the organic PROMIX starter soil they have been amazing until this issue. The only thing that changed was I STOPPED giving them the cactus nutes (2-7-7) about a week b4 transition. I did transplant into a container twice the size just to be safe…and that brings me to… @Tr33 thanks so much for all the effort m8. I sincerely appreciate it. When i was looking at the roots, as I untangled rocks and sand pouches i didn’t notice any noodling. The roots looked to be long and lean. Maybe a little yellowish for my liking but other then that, nothing noticeably visible when I was inspecting them. They seem to be very flat flowers that are starting…


That’s the leaf issue close up. I have another also…

All I can do is hope and pray that they turn out like the widow I harvested in June. Crazy crazy situation but the flower was top notch. People thought it was Indoor…


#20

@Countryboyjvd1971 so here a question that I’m having trouble with… how come the other 4 that are in the exact same soil,water,nutes seem to be doing AMAZING but this 1 is being finicky… here are her cousins…


I know they are all different and some require different things. What could I apply to her water to reduce the PH?? Is there anything round the house that I can use?
Maybe the man who called my nitrogen poisoning on another post could chime in… @Majiktoker Any advice sir?
Thanks again for the help guys. I just want my ladies happy and healthy. They are like my 4th-8th kids…hahaha
