Purple stalk and purple on parts of the leaves

Emilya i am looking at this one a bit too long so i would like others to jump on , its hard to tell if its running hot or the low end ph

 

[NuttyProfessor]

@VetSmoke85 on same time scale, your thoughts , ?

Hiya! I'm not great with these things but to me the symptoms could point towards a P deficiency. But lots of issues look the same to me So maybe a pH issue. Even though your pH for the feeding is in range maybe the soil is off. I had a lot of problems when I added worm castings to my soil. Think I added too much and it caused a problem. Fed with plain pH'd water getting about 20% run off for a few cycles and things picked up again.

yes but peat is very acidic and in the 4s , bat guano can drop too to very low levels thats why i wondered

Fresh guano has a pH of 5.1–7.3, making it neutral or somewhat acidic. However, as it ages, the guano becomes strongly acidic, reaching pH levels of 2.7–4.1.

most peat base mixes use lime so the ph balance out , buffering

edit i answered to quick , my dog was melting my head to get out lol

so its coco perlite and amendments maybe just plain water for a couple of goes see how it goes i see a bit of burn but not much, small plants don't need much burn to have problems or lock outs . you need this sorted before even thinking of flowering .
the rust/gold stripe remind be of ph fluctuations ,

right im off again , be few hours until i get back ,

Morning brother. I truly appreciate all you advice and will look further into the pH levels.

Morning brother thanks for the reply I'm definitely gonna look into my pH ah little harder. I'm gonna do ah flush n check my runoff and go from there.

 

[bluter]

just what is your media ?

i see mention of coco and perlite. your ph is way high if that is the media. the guano and worm shit isn't going to help either. they don't work the same in that media. it's more for soil based and will throw your nute schedule off.

seems like you are mixing two different grow styles.

 

[VetSmoke85]

Maybe a slurry test would be useful?

runoff really doesn't tell you anything. it's the inputs that matter.

I didn't know bat guano and earthworm castings is only for soil. Didn't think I was mixing two different grow styles. What should I do I wanna flower in the next two weeks?

 

[bluter]

ride it out i guess. go easy on the nutes.

also i believe gaia green is organic based - also not the best for this media. coco /peat / perlite is considered a neutral or hydro type app. organics like the gaia green and the poop aren't really suited.

we need someone like @Emilya to pop in and straighten some of the basics around a bit.


edit: also don't panic. nothings on fire. i don't see heart stopping issues.

 

[Pat Puffer]

Yeah...coco + peat means you are soiless medium. Your nutes at >6.5 will have problems being absorbed.

Bluter and Nutty are on it. You appear to have cal&mag issues. Maybe due to pH? Could be due to mixing organics and soiless. @NuttyProfessor is doing this kind of run (coco&organics) with great results. However, he is a bit more ahead on the learning curve.

Given your medium, I would flush and stary anew with pH'd inputs for your current medium.

 

[Emilya Green]

Some organics can indeed work in coco... geoflora is one of those, because everything comes with it, the minerals and the microbes. Water based hydro systems wont work, because there is nothing to latch onto. In this case, I would say that the gaia stuff isnt working so well, probably due to a lack of the correct microbes, and that pH is definitely a factor in getting the needed non organic supplements to the plant.

Looks like a classic case of simply under fed. Water thoroughly till run off then feed full strength all this ph talk gets old after a while. Have you ever seen mother nature pull out the ph pen or up and down?

Have you ever seen mother nature grow in a closed container?

 

[BeanTownFan420]

Have you ever seen mother nature grow in a closed container?

My comment was rhetorical!

 

[BeanTownFan420]

Yes it is called a micro climate environment many are found throughout the world where the vegetation and fauna have stayed the same for millions of years without interacting with anything outside there little box.

 

[BeanTownFan420]

Have you ever seen mother nature grow in a closed container?

Yes she grows the Wollemi pine in such a container trapped in time.

 

[VetSmoke85]

So you're saying if a weed plant was planted in highly acidic or alkaline soil but the micro climate (temperature, humidity, wind etc) was suitable, it would grow fine?

 

[BeanTownFan420]

Cannabis grows in all soil types and conditions through adaptation so over time yes it may grow fine. Cold regions at higher altitudes she grows into indica wider leaves that hold more heat and catch the lower angle sun at higher altitudes in the tropics she thins out to release more heat and catches more rays easier at the equator so her leaves are thinner.

 

[VetSmoke85]

But isn't that a bit like saying they adapt over time so just stick whatever form of nutrients in there that you like and it'll be okay? I'm not trying to argue I'm just trying to understand your point.
