My babies have a deficiency...which one though???

[ZeusOGrefugee]

Hello all you good folks, I currently have a grow thread going in the Grow diaries forum and I seem to be having a slight nute def. From the looks of it, I think it is a K def, but not sure. I am growing in soilless medium and ferting with AK fish emulsion. I am using AK glacial spring H2O, so the PH is not an issue...here are some pics. please, any advice would be helpful...Peace

 

[Brother_Monk]

1 tsp epsom salt/gallon should clear that up.

How doo you know Ph is not an issue? By soiless, do you mean peat based? Coco? Use the link in my sig to give us better info.

Peace

[ZeusOGrefugee]

thanks, but what is it????

 

[Brother_Monk]

First thing...it is wrong to assume someone is going to go searching for your thread, looking for information YOU should be providing US, for a diagnosis of your problem. Perhaps with some better info, we could give you an accurate diagnosis. If you want a snap answer, I'm sure someone will come along and take a stab at it. It's like going to the hospital and saying to the doctors...I'm light headed and dizzy. First thing they will ask is what medication you are taking, if any.

My advice is....give us more information.

Peace
BM

 

[MTF-Sandman]

^^Yup...the more info you give, the better the answers will be.

Looks like a mag uptake problem to me...

 

[ZeusOGrefugee]

Hey Brother Monk...WTF, why do you have to be an a-hole??? I was simply stating that I had a current thread going, I dont expect you to go looking it up fpr more info, I gave you the info you need in the first post. What more do you want?? I am using AK fish emulsion for vegging. The plants are 1 month old now. Just fed them a few days ago w/ 1/2 strength nutes...The strains are Blu Moon Rocks, AK48, NL and Blu Mystic. They started to show a little def. the day before i fed them, it has gotten worse since then, but not terrible. Seems to have stopped now, but I just want to know what it is, so I can learn from this... This website is supposed to be for support of your fellow growers, and to help them grow this most sacred of plants. I think BrotherMonk has lost site of this fact!!! If anybody feels like giving me some advice about this plant prob, please do. If you are like Br Monk, go post ur shit elsewhere...

 

[MTF-Sandman]

He's not being an ass...he's trying to help you get your plants straightened out. There's some MAJOR stuff you left out that could be causing the problems...like PH, nute PPMs, Medium details (with NPK and amendments), temps, how often they're getting fed, how much, etc.

This kind of info helps build a better picture of what's causing the problems vs. just diagnosing the symptoms that are showing.

BTW, ditch that Fish Emulsion and get a complete primary nute...fish emulsion is LOADED with heavy metals (like arsenic, cadmium, and cobalt to name a few) and doesn't contain enough P, K or any mag or micros. It's fine to use as a suppliment if you've got an N def, but that's about all it's good for.

 

[Black Ra1n]

I agree with MTF .. get away from the constant fish feedings and get a good all round food, they need some micro's.

 

[NuggyBuds]

it's a mag deficiency.
Could be due to the water you are using, get some calmag plus or something like it.

Most likely a PH problem however, do not assume because you are using spring water that it is a good ph for plants, your ferts and medium can be effecting your final PH you need to test both before you water and after, this way you can verify that your medium is not causing a drop in PH.

From an old thread on an other forum by user bald1

How to test the pH of your soil mix

Measuring the pH of soil is just as important as with hydro applications, but few people know how to test soil pH to see if it is within the optimum range for growing robust healthy plants. Here I will try to explain my method of testing any soil / soilless mix, enabling me to spot any problems and correct them if necessary.

Firstly, wait till your soil has dried out and is due for its next watering schedule. Then take some plain water that you usually water your garden with, and adjust the pH to 7.0. You must make sure that you know the exact pH of the water going into your soil, and the neutral 7.0 is best, but anywhere from 6.5 – 7.0 will suffice.

Then place your pot into a bowl of some sort to catch the runoff water, and then start to water your soil slowly (with your pH- corrected plain water) till the water starts to drip from the bottom.
It’s the first drops of water that will give you the best reading of your soil, so make sure to water slowly till you see the first droplets. Then remove the pot from the bowl to eliminate excess water entering the bowl. Then perform the pH test on the runoff and compare it too your initial test.
The results of the runoff test will likely be lower than your starting value of 7.0. If this is the case, a small drop of 0.5 pH to 6.5 pH (example) would be ok and your soil needs no further alterations at the moment. But that’s not to say that it won’t need any future tests at all, just not at this time.

What if the pH is off?


If your results prove to have dropped considerably, say to around 5.5 (which can happen in late stages of flowering), you will need to add some lime into your soil to help buffer the pH back up again.

Remove the first inch or so of soil, taking care not to damage any roots whilst performing this task. Then sprinkle the lime into the pot, nice and evenly at a rate of 1 teaspoon (5 ml) of lime per gallon of soil. Then replace the soil you removed earlier, and saturate the soil good to wash in the lime.

Do the same test next time your plants need watering just to check that everything is fine, if more lime needs to be added then just repeat the process again till you reach close to 6.5 – 7.0 with the runoff.

Ensuring that your pH is correct should be done throughout the life cycle; this will help eliminate any nutrient lockout that may occur. I recommend doing this once a month just to keep the PH in check, and you should never have a problem with deficiencies caused by pH lockout.

Thanks all. I guess Ill have to check the PH and Im gonna order some Earth Juice stuff right now. Mag. def. , huh?? Funny, Ive never had this prob. with fish emulsion B4...

 

[Brother_Monk]

You must spread some Reputation around before giving it to MTF-Sandman again. I'll getcha soon as I give some to Zeus.

How about something more like this buddy.

BrotherMonk - didn't mean to offend you, I just felt a tone in ur first post and I was havin a bad day. Maybe with some more info, you guys can give me a better answer.
Here is my thread:

http://www.icmag.com/ic/showthread.php?t=47817

My temps are in the mid 60's at night, maybe a few degrees cooler sometimes, as it is -40 outdoors here!! With the lights on, they are prolly in the mid 70's. Maybe a little cool, but they seem to like it OK. Im in ProMix soilless medium with nada added. I started using just AK fish emulsion(5-1-1), but just ordered some EJ products...Grow, Bloom, Catalyst and MicroBlast. Those should help with any deficiencies I am having. These babies are all from seed, 96% germ rate...They are a month old, and are getting a transplant into 2 gal grow bags on Monday. Then a good dose of new nutes. Thats about it. I dont have a PH meter, so I cant tell u the PH of the water or runoff, but I know the water has been tested at around 6.5-7.0, so it should be OK... If I missed something, let me know, and I still wanna figure out this deficiency. Never had problems before, but also this is the first time w/ promix 4 me...I may get some Mycchorizzal stuff too.Thanks all, and BroMonk, sorry aagain!!!

^^^Plenty more good info in NuggyBuds post^^^ I think you should be getting the point by now. Hope the new nutes do the trick for ya Zeus. BTW, no offense taken Everybody gets their turn at being the A-Hole. My post may have annoyed you, but it wasn't designed to do so. I'm here to help, and have learned not to let childish tantrums, sway me. If you do not concur with the consensus...then do what you will. You have your diagnosis. You should consider at least getting some ph test strips. Flying blind is no picnic, for you, or for us.


I'll see your mag deficiency, and..... raise 'ya some calcium.

Peace

[ZeusOGrefugee]

So I take it its a Mag def.!!! Thanks all for the helpful advice. I got the EJ products comin on Mon, as well as 2 gal grow bags for the transplant. I gave them some more nutes yesterday, along with some AK MorBloom for some P & K. We'll see how they do over the weekend, then Monday they get the transplant...Peace all..

 

[ZeusOGrefugee]

SO, I hate to say it(not), but I dont think it was a ph or magnesium prob. I gave them another feeding 2 days ago, with some Mor Bloom for Pand K, and when the lights went on today...!!!!WOW!!I'll let the pics do the talking for me. I guess they just needed some more P and K...check it out, and my new light setup.... Thanks all for the help...

 

[NuggyBuds]

Hmmm. well if you added EJ bloom and stoped using fish emulsion then you DID fix the PH problem.

magnesium shows a deficiency in acidic ph environments (between 2 and 6.4)

EJ bloom contains;
Bat and seabird guanos, oat bran, sea kelp, potash, steamed bone meal, and rock phosphate

rock phosphate tends to raise ph.

both p and k deficiencies manifest as leaf tip/edge burns and curling.

your plants show either a mag def. or calcium def. or both.
probably both since calcium locks out in acid soil (also between 2 and 6.4)
this is why I said it was a ph problem.

SO, I hate to say it(not), but I dont think it was a ph or magnesium prob

a little rude don't you think I mean we are all trying to help here. You asked for opinions on the problem, and MULTIPLE people tell you your problem, and then you think you've got the answer yourself.

Fish emulsion is acidic. <------This is your problem.
