Couldn't decide what I have got going here...

I couldn't pick either nitrogen def or pH problems...
Help please!

I'm in all organic. Suby's mix.
60% peat
30% perlite
10% EWC

2 table spoons / gal blood and bone mean (Mixture is 4-10-0)
2 table spoons / gal dolomite lime

I water with a tea of 1 table spoon kelp meal (0-0-5) and 2 table spoons of mollasses / gal of water.

If this is nitrogen, I want to use urine to fix the problem.
I'm at day 22 flowering, what ratio would you suggest?

Leaf left on plant:




Worst leaf that had to be taken off:

Hi m8
I aint sure u have anything to worry about m8(but make sure u get 2nd/3rd/4th opinions first)*smileS*

Looks like your a few weeks into flower.I honestly dont think u have a problem....The leaves have served there purpose.Time for them to die and let light penetrate better...

There from a cutting yes?
Can see the leaves have a reverted Leaf pattern...Again i think the fact some only have 3 blades would of limited there lifespan....Plus if there 3/5 bladed leaves they must of been on the plant a while now....


I see a lot mention urine
Isnt it easier(less fiddly)To just use a organic fert from a bottle?

I would have no quams about useing urine(Hell we use other animal shit(So the thought of My Pee in the soil would not put me off at all))

Just think it be easier to open a bottle of ferts and use half a capfull or somit*smiels*


Bottom line for me
U have nothing to worry about
If u do want to try and fix them(not that i think u need to)
Dont do anythign till the others advice(not that u plan to anyway)

Good luck m8

wow, that feeding mix is never going to work.

I can't quite tell what you are feeding but it sounds like a pure potassium mix...

you should be aiming for a ratio of NPK 50 : 100 : 150,

Also, if you don't actually know what your ph is then it is bound to be wrong.

You cannot grow properly without knowing the ph so get a ph TESTer or you might as well chop your plants now...

Have a look at the recommended ppm levels you should be aiming for here: http://www.angelfire.com/cantina/fourtwenty/articles/profiles.htm

It lets you work out the ppm of each nutrient in your fertilizer too and thus helps you find the exact ratio of ferts to feed.

Start with ph. Since your growing in 90% soilless I would use 5.6 to 6.2 as my target. Directions for testing are in my signature.

Looks like in picture 1 at the top, your getting purple to red petioles and stems. Describe that more.

How long have the plants been in this mix? Repotted recently?

Tunefull - I don't like to have to make a trip to the nursery. It's about 30 minutes away.

How is it pure potassium?
The nutrients in the soil are 4-10-0.
I feed a tea every second or third watering with 0-0-5 to make up for having no potassium in my soil mix.

I tested my pH about a week 1/2 ago I believe. It was 6.0 - 6.5 (Hard to read those damn test strips).

I can attest that the stems are turning purple/reddish, but my the flowers are getting only a small tinge of color to them, to which I believe is cold temps (Never gets over 72 F in there anymore, it's usually around 68-70 now)

The plants have been in the mix since they rooted (about 2 months now) and were repotted 23-25 days ago.

easily nitrogen issue, your nutrients are slow acting even if mixed into a tea, they becomed a bit more readily available

you need more ntirogen in the plants diet

there used to be a urine thread on overgrow, i never did save it i wish i did
isaved loads of threads in to PDF formats but never got around to doing that one

it was called the urine thread or pee thread something like that
 
urine? lol

thats a good fix on the fly but to use that as a normal nute is nasty and dirty. but if your lazy white trash then i guess thats ok. you can get N in organtic additives that is much better for your plants than urine.

How is that nasty and dirty?
Urine is sterile...
Do you condone the use of animal shit, but not urine...?
That's kind of strange if you ask me.

However, I do plan on adding some kind of additive with nitrogen in it to mix into my new soil I'm cooking up... possibly compost some grass clippings.

Thanks for the input everyone.

Yes i agree it is no more dirty than useing animal poo...As i say that would never be a issue(Lol got to laugh at those who turn there nose up at it really)
but i just dont see it being very practical...Unless u mix a lot at a time..Like i would not want to go thru the whole procedure every time i water/feed..

But hey each to there own,It would not suit me.But is things i do that dont suit others...I always belive there is no right/wrong way to do somit*smiles*

Okay. So the lime is fresh and not been hanging around too long. 2 tablespoons per gallon is alot of lime. I bet this is 17 pounds per cubic yard or 27 cubic feet. While the peat required lime, the perlite has a higher ph around 7 or more to start. So, it does not require any. I think you may have overlimed. You said the ph was 6 to 6.5. If it is 6.5 then its high for soilless mix. Phosphorus deficiency can be created in a soilless mix as the ph rises. Micros except molybdenum can decrease in availability. You need to invest in a cheap digital ph meter.

Hi Natural, doesn't matter if the soil contains alot of other nutrients. If you are only feeding potassium, the soil will eventually get depleted of the other nutrients.

By the looks of your leaves that has already happened.

You need to be feeding the right ratio so that your soil doesn't get depleted of nutes. You are relying too much on the soil to feed your plants but fertilised soil is more of a back up in my opinion. If you are not feeding enough of a nutrient, as long as the soil contains that nute the plant won't become deficient in it. But if you cut out a nutrient completely the soil will try and make up for that fact but will not be able to feed the plant for ever.

In hydro you have no back up whatsoever and need to get the ratio spot on but I'm telling you, even in soil you need a fairly accurate ratio or things will start to go wrong.
