Asshole plant with yellow spots

[Mrs. Greenjeans]

Would someone mind terribly taking a look at this plant and taking a guess as to what it's major malfunction is?

My guess is either boron deficiency or light burn. The thing is, it gets the exact same treatment as all my other plants, but it's the only one that ever acts up. I'm starting to hate it. I'm going to experiment on it Frankenstein style if it doesn't shape up. It'll be my guineaplant.

Sorry the pic is really fuzzy but the caption says 'how am I supposed to water this thing?'
:D
It's an asshole plant.

Anyway I would guess a couple things... those patches COULD be an advanced Mg def, but they are kind of irtregular, so hm..

MY first place to start would be that your soil wasn't really that well mixed and you've got a 'hot spot' of crap pH. A good thorough flushing is a good place to start, and check your runoff. The curled-under leaves too would indicated that it's time for a flush anyway.

The fact that you see the spotting only on older leaves is good. It may just be scars from damage from a problem that no longer exists (flush anyway just in case!).

[Mrs. Greenjeans]

AHAHAHAHAHAHA! I love it. I'm saving that pic.

Once again, Stinky comes through. Thanks Doll. I was supposed to check pH yesterday anyway, and just got lazy.

I might go 12/12 today. I have approximately 43 minutes to decide. I like to start things at noon and midnight. That way even if my timer malfunctions, I still remember to turn lights on and off.

[Mrs. Greenjeans]

Oh, I meant to say:
Could it be time to flush already? I just transplanted on the 1st, a week ago, and it's only been fed once. Also, these spots didn't "develop" kwim? I went to bed, everything was fine, I wake up, SPOTS.

Then I would look at heat/light burn as the culprit

[trynagethigh]

LOL@stinkys pic...LOL..stinky you are a mess..:)

[stinkyattic]

LOL..stinky you are a mess..
I'm even better in person.
Ask my girlfriends.
Last night I swear my friend almost squirted wine out of her nose over some stupid comment I made. It would have been a disaster. She was wearing a white shirt. It was red wine.

[Zandor]

No that is NOT heat burn or light burn.

Ph is so important to a successful grow I can't stress that enough.

What type of water are you using and what nutrients are you feeding them and how much. You have other problems you need to fix before you switch to 12/12.

That is if you want any yield to speak of and even the plant to live to finish.

[stinkyattic]

No that is NOT heat burn or light burn..
Hey, that was my only suggestion for a necrotic patch that appears in the space of only a few hours from a healthy plant to a brown patch.
I stand by my original diagnosis that it's a pH hotspot from poorly mixed soil and earlie symptoms went unnoticed.

[Mrs. Greenjeans]

I'm using tap water actually, but I always check the pH on it. Both soil and runoff are hitting 6.8-6.9 consistently. There's an airstone in it, and I let it sit for 24 hours before I use it. Temp 70F.

The only nutes I have access to is Miracle Gro 24-8-16 (ask Stinky about the issue I have getting $$$ out of the old man). I feed 1/4 teaspoon per gallon, every 3rd watering. Only water when pots feel light. The rest of the time I mix 1 tablespoon epsom salts in a gallon of water. They get that about every other watering.

It's pertinent to know I'm not growing to sell, just to save money. The man is a heavy smoker. This is my first try, basically an experiment. If I decide to stick with it, I'm hoping to get a system in place whereby I can average a yield of 2oz./month. That's about how much he smokes, sometimes more, but that's about an average. An extra 200$/mo. would go a long way toward saving money for home improvements on the nearly 100 year old house we're buying, kwim?

[stinkyattic]

Shit that Miracle Grow on top of being crap fertilizer is also not the right proportions of nutes for your tender babies. The N is relatively way too high and you are going to (if you don't see it already) see that new growth is softer than it shoud be, dark green, and susceptible to pests/damage.
That being said, and the pics, it looks like you have a salt buildup. Either way, time to flush. I can;t believe that it looked fine one day and crap the next... I'll betcha that last week you didn't notice pale banding between the veins on the older leaves.
Did you know it IS possible to scrape together a grow from cheap walmart fertilizer sources if you have time to dick around with it?
In spring they will have blood meal and bone meal on the shelves. Plus they sell Schultz specialty fertilizers like cactus, orchid, bloom plus, etc. that have micronutes in them but honestly in the end you are better off squeezing $15 out of the ol man and going for some pure blend pro grow organic.
If you go the cheap route, I'd suggest buying the BOG 'Bonanza of Green' book where he gives his walmart -based dirt recipe, lol... sam's choice dirt, bone meal, and blood meal in varying proportions for different life stages. Or you can go see if his stuff is over on ICMag.

[Mrs. Greenjeans]

I'll check ICMag. That's a good resource for a lot of things I've noticed.

Okay, well I've decided to go 12/12 anyway. Can you recommend a bloom fert? See, if this is a decent enough experiment, he'll come up off the money for the next go-round. Right now he's leery. He feels like he's being double dipped, cause he's still buying weed, and shelling out for a grow op on top of it. He's never been this miserly before. I think it's cause he had to borrow against his retirement to put 5% down on the house.

[Mrs. Greenjeans]

Wheee! Okay, I found the mix on ICMag.:)

[stinkyattic]

Can you recommend a bloom fert?
.
My first bloom fert was shultz bloom plus from home dePOT.
Now I use Power Flower plus TopMax.
Well now I don't use anything because I have no plants... but....:jointsmile:

[Irie1]

Seriously, my first reaction is that your plant is over watered. Make sure the soil dries out occasionally. I have had this problem in the past with really dense dirt. Make sure you use plenty of perlite, or light warrior. Good luck!:hippy:

[Mrs. Greenjeans]

Thanks all!

[Mrs. Greenjeans]

Is bloom fert with 15-30-15 too high in N?

[Bree1978]

That is what I have been using but at 1/2 strength...my opinion? It will get you there, but is NOT optimal....Bree

[Mrs. Greenjeans]

Thanks Bree!;)

Ms Jeans, as long as you're using fresh, top quality potting soil there should be no mineral definceincies and I have yet to see a reliable test for us commoners to test for such probs, unless you have a connection with the local agriculture engineer. I have to agree with Zandor here and call it a PH problem. Lack of micro nutes and minerals just don't cause such problems in every day life , especially in a plant only a few months old from birth to harvest. If those were mine and I saw such damage I'd invest $22 in a Brita Water Filter. It's a miracle tool made for us that changes bad tap water into a wonderful elixer of life!

[foxysox]

Heya greenjeans!
Get your N number down to half or less of the veg fert you were using.
If you're stuck with that stuff, yeah, you could dilute it but then you are also losing out on micronutrients etc.
Are you on city water? If so, your water should not be causing pH problems. The city sends it out close to neutral to avoid corroding the pipelines. Almost guaranteed it's a soil problem.

[madeline]

Umm, the PH out of my tap water is off the scale, ++9, and it's city water. N overdose usually shows with a burned and crusty outter edge of the leaves. Spots starting from the center and working out are usually a sign of PH being off-kilter, in my experience.

Heya yerself Miss Foxy! ;) In my growlog, I mentioned that I did a little research, and found out the water in my particular neighborhood comes from a particular reservoir, and the average pH is 7.8. However, I called the company that manufactures the largest part of the soil mix I am using, and they say their product has a pH of 5.5. When I tested my runoff and soil they read 6.8-6.9. I'm guessing they're balancing each other out.

Schultz has a couple of different formulas. What do you think of the 5-30-5?

The old man has a migraine and is passed out cold. I'm considering ordering the fancyschmancy organic stuff that Stinky Attic mentioned, and then confessing later.

It is easier to obtain forgiveness, than permission. ::evilgrin::

Man, cannabis cultivating is not for the faint of heart, or the slim of wallet.

Thanks for the input Madeline! I should get one of those anyway, just on principle. I rarely drink water, cause I hate the way it smells and tastes. Like a compost pile with bleach in it. I need to drink more water, and I am more likely to do it if it's filtered. Right now I'm spending too much on bottled water for drinking.

[stinkyattic]

When I tested my runoff and soil they read 6.8-6.9. I'm guessing they're balancing each other out..ROFL you have like self-balancing water!!! That 5.5 number is showing up in that spotty thing. You probably have a pocket in there that didn't get enough lightener and the roots are just reaching it now, but the water isn't running through it properly. You could always stick the whole pot in a bucket of water and let it soak for a little while, then drain it out and see if things stop gettting worse.


Schultz has a couple of different formulas. What do you think of the 5-30-5?. Not too bad, and better if you can get a source of potassium in there to protect the plants from disease.


It is easier to obtain forgiveness, than permission. t.true dat.

[Mrs. Greenjeans]

I believe I will try soaking it. It's time for scheduled flushings anyway.

[kindprincess]

you can use granite dust to add instant potassium, bananas are good in home made mulch, and the simple solution (if you hadn't transplanted already) would be potash.

hi stinky, i'm back for a while... til i get called out again, lol

[Mrs. Greenjeans]

Hi KP! Lovely to see you!
I'm intrigued by this homemade mulch you speak of. Tell me more...

[kindprincess]

do you have a mulch barrel? if not, a large screen about two feet off the ground will work. this takes about a year, but is well worth it, imo.

basically, you throw your plant trash (ie, grass, hedge clippings, old veggies, fruits...) in the barrel or on the screen. the key is aeration and agitation. mix about once a week, the compost will rot, and you'll end up with very fertile mulch.

keep in mind that 100% mulch is too hot for pot plants. mix about half and half with a good potting soil or soiless mix (perlite, vermiculite)

i've been composting for more than 15 years now :D if you forget about it for six months, no sweat!, just mix and let sit and mix again, and you're good to go.

if you do the screen thing, your final product will be what falls under the screen. you can scoop it out with a shovel.

kp

[Mrs. Greenjeans]

Ohhh, a compost pile! LOL! I have one of those. Two actually. Sorry, I thought you were talking about something else. Brain fart on my behalf.
Right now my compost pile is under 8 inches of snow and ice. I live in the midwest.:p
