Cheese: Dr. They're Lookin Sick

[spiritlevel]

Hello

I'm after some advice. I'm currently blooming Cheese and they are on Days 18 & 21. I have 6 in total; 4 are a few days ahead as they entered the bloom room first.

I have a link to my grow journal in my signature for any additional info. Post 22 shows a host of the most recent pix indicating the problems.

Any help appreciated, thanks

Nutrient def, primarily Nitrogen, probably exacerbated by the cramped quarters you've got the plant inhabiting.
Larger pot, complete a soil runoff test to ensure pH is not adding to your woes, and don't worry TOO much about N def late in flower, since that's normal. Yours is starting early, though, and without a re-pot your yield won't be at its potential.

As suggested above don't over do it,, but those plants need some feed man

A single feed of Iguana Juice bloom or any other bloom fert with a high level of Nitrogen should help.

all the best

Looks to me like those pots are way too small for a plant that big first off.
Spots on leaves - look like nute splash.
Lower leaves yellowing - either not enough N in your solution or you didn't have enough when you making the switch from veg to flower. Although lower leaves yellowing is normal, its not normal this early into flower.....

What will a 'soil run off test' consist of?
I only have tap water to use, will I have to do anything to it?
Will I have to test all pots or just a couple?
Is there much point repotting at this stage in bloom; i.e settling in time?

If you could answer my queries above I'd be grateful.

I've been feeding them on quite a high EC. I suppose giving them just bloom feed without all the other amendments might be a good idea. My first thought was nitrogen, but when I looked at the sticky in the infirmary I found symptoms of what I thought were/are other things. cheers

I have been careful on every watering since I first potted them not to get the leaves wet during watering. I don't think its that. The plants were quite green when I brought them in, i just assumed it was an indication that they were healthy. Over time they have just kinda gotten yellow/light-green. With red petioles and stems. The reddening has actually started to subside since their last feed.

Strange thing is I've grown much much bigger plants in the same size pots on a grand scale, and not run into this problem. I've sighted a thread elsewhere where someone compares root development with plant growth. Their results kinda concur with my previous results to a large degree.

My previous cheese attempt in pots more than twice the volume also suffered the same deficiency, though not to the same extent. Though I do have a friend who too grew some of this very strain from the same mothers who suffered the same problem on a very pronounced scale who claimed magnesium was the culprit. I don't know where he got his information from and he isn't one to ask many people.

Thanks for all your replies, I still don't know what to do. I may repot depending upon stinky or more opinions on that matter, and also try giving them a high EC of just bloom ferts with no additives. Feeding day is tomorrow so any more opinions most welcome

** to add, what about my redenning?

Well, since they have no other problems and are in this stages of flowering, unless dosages of nitrogen does not fix the problem a pot switch has to be in order, when you are in flowering you want to not transplant if all possible; but somet3imes it's completely necessary for the plant to finish depending on how bad it is.

In this situation it's just a common nitrogen problem, give some nitrogen, but use it sparingly, half dosage of what you would use in veg and use it with your bloom fert if it does not have enough nitrogen and use it till a week or 2 before harvest.

I will purchase a nitrogen amendment tomorrow. I don't think I have anything on the shelf with sufficient amounts, I'll go and have a look

 

[spiritlevel]

I've looked on the shelf, I've decided to list the NPK of each product which has the NPK on the label.

Mother Earth Grow - 1.5 - 0.75 - 1.5
Mother Earth Bloom - 0.5 - 1.5 - 2.0

Sensi Grow A - 3.7 - 0 - 0
Sensi Grow B - 2.5 - 2.2 - 5.7

Sensi Bloom A - 4.3 - 0 - 3.1
Sensi Bloom B - 1.5 - 4.6 - 5.7

Humic H2 - 1.0 - 0.75 - 1.5

Fulvic F1 - 1.0 - 0.75 - 1.5

Big Bud - 0 - 1 - 4

Overdrive - 1 - 3 - 4

The other products do not indicate to me an NPK (Barricade Potassium Silicate & Carboload & Voodoo Juice)

From what I know about math, which is not a great deal, I should be able to just add the ratios of NP & K together? Am I right. So, if I was using

Mother Earth Bloom - 0.5 - 1.5 - 2.0
Big Bud - 0 - 1 - 4 then I'd just do

N -> 0.5 + 0
P -> 1.5 + 1
K -> 2.0 + 4

Is that right? Is 0.5 - 2.5 - 6 my resultant NPK ratio, providing I added the products in their prescribed amounts?

If it is, then I ought to be able to calculate the resultant NPK of the full combination of products assuming I add them in the prescribed quantities. I could be wrong, I dunno, but if that is a correct way to determine a rough guess of the NPK in a solution then I can almost see why I would be having a Nitro deficiency from the product lineup.

Any thoughts and comments welcomed fellow gardeners as I'm still trying to figure out where I went wrong, or am going wrong, in my methods of growing bud.

** I do have a bottle of Formulex which appears to have a high Nitrogen content according to the 2.4 - 0.9 - 3.4 NPK ratio on the bottle. I was regularly foliar feeding these plants when they were vegging with this stuff.

Thanks again!!

Every one must have a job lol... I couldn't wait for anymore feedback, I had to give them something today else they would have dried up.

I agree with those who say there is a Nitrogen (N) lack. The physical characteristics of the deficiency are very much in tune with what occurs toward the end of bloom. To add to that, when I look at the NPK levels of what I've been feeding them, though the EC/PPM has been in range, the overall balance of the mixed nutrient solutions' content obviously doesn't possess the right set of available elements that the plants require. A bit like living off a big mac and fries for a month or two then realizing ones dietary requirements have not been met by way of developing and illness maybe.

So with that in mind (the plants dietary requirements) I've looked on my shelves to see what I could amend my nutrient solution with to increase the (N) content.

Mother Earth Bloom - 0.5 - 1.5 - 2.0
Sensi Bloom A only - 4.3 - 0 - 3.1
Big Bud - 0 - 1 - 4
Formulex - 2.4 - 0.9 - 3.4

Carboload was also added, the EC was 1.6 and pH 6.68

There is clearly much more (N) in that meal than:

Mother Earth Bloom - 0.5 - 1.5 - 2.0
Humic H2 - 1.0 - 0.75 - 1.5
Fulvic F1 - 1.0 - 0.75 - 1.5
Big Bud - 0 - 1 - 4

Plus Carboload, and Potassium Silicate which they had been getting.

I'm quite sure from that info about (N) from you helpful folks, and the NPK levels on each bottle, and a lil mathematics, that I'm hoping is right, shows how I've come to have an (N) deficiency.

** [ if i can just add the components then the resultant NPK would be around 7 - 3 - 13 {4.2.7?/3.1.5?}, compared to the 3 - 4 - 9 {1.1.2?} (I dunno I've my calculations are correct but it the only way I can try and get my head round the deficiency and what I did/didn't do) ] **

Adding only 1 part of a 2 part (the Sensi) is not a good idea. The 2 parts are meant to work together to give the plant what it needs. You could end up with some weird problems by doing that.

I may have fucked up then, the ext couple days will determine...

But I did put other stuff in too if thats any consolation.

Dr, they ain't sick no more woop woop

Good to hear, I must of missed this thread again sorry for not getting back to you after your reply, normally I am very quick to reply back; but good to hear you got it fixed.
