Yellowing question

[sensilights]

Hello I uh found these pictures on the internet somewhere but i was wondering if y'all might be able to tell whats wrong...i have an idea that it might be a possible zinc toxicity? and heat stress on the second one?
anyways the first 4 are the same plant
the next 3 are a different plant 2 of the pictures show the results 4 days after a FIM that i think may have missed *if thats possible* lol
Any help is appreciated :)

the last 2 pics will be in a second post :)

I really doubt zinc toxicity is your problem. It'd be a good idea to fill this out: Troubleshooting form (http://boards.cannabis.com/plant-problems/127058-troubleshooting-form-yay-you-know-you-wanted-one.html) That'll give people a good idea what you're working with, and what might be causing the problems. Pic#3 looks N deficient, but before you go adding more Nitrogen, you'll want to know if anything else may be causing lockout, like unstable pH, salt buildup, or the like.

Mr C he has to track down whoever actually took those photos he found and ask them ALL those questions.....:D

LOL, ah yes.

Sensi- Get your 'friend' or anonymous internet poster to fill out the troubleshooting form for his, *ahem* 'tomatoes', and we'll be glad to lend 'him or her' a hand! :jointsmile:

[Mr. Clandestine]

A lot of water softeners add fairly high amounts of sodium that can be harmful to the plant, and many of them also remove calcium and magnesium from the water... both of which are essential nutrients. I'd do a light soil flush with pH'ed (preferably regular tap water), or distilled/RO water with CalMag added. Afterwards, give them a light feeding with a complete (and water soluble) fertilizer. Get yourself a quality fertilizer that's higher in nitrogen than in phosphorus and potassium to use if the yellowing worsens. Start with very diluted feedings (only 1/4-1/2 of the recommended strength) and work your way up from there until you start seeing a difference. It would also be a good idea to check and make sure the most badly affected plants haven't become rootbound in their pots. If they have, repot them into larger containers with fresh soil and preferably some extra perlite. Scott's soil is OK for growing, but it's not ideal with the time-released fertilizers and moisture retaining agents. Cutting with extra perlite will greatly enhance the drainage of the soil.

Your Epsoma fertilizer is a good soil amendment, but you'll periodically need to supplement with soluble fertilizers that have either been depleted by the roots, or haven't yet had a chance to break down. I've never used this particular fertilizer, but I have one of their similar products that contained mycorrhizae/beneficial bacteria, and had great results with it. It also had a similar NPK to your Plant Tone, and the plants really seemed to love it.

Also, warm air rises... so it might be a better idea to pull your cooler intake air in from the bottom of your box, and exhaust out the top. If you're able to do so, that is. Try to keep your 'daytime' temps below 80F for best results.

Thanks Mr C! I'll update in a day or two :D

[sensilights]

Well almost 72 hours after the flush it looks like color is returning...the pale green is *at least it looks like* starting to turn darker again...will update with pics soon


So...Thanks for the help :D :thumbsup:

[sensilights]

BTW the flush was done with melted snow which was boiled *to kill any kind of baddie that might lurk there* then allowed to cool to room temperature. Around a gallon was used for a 4"x4"x4" pot. The other gallon or so of melted/boiled/cooled snow *with just a few drops of palmolive in it*is now being used to water them and they look just dandy :)

[Mr. Clandestine]

Glad to hear things are starting to clear up for ya. :thumbsup:

I can't remember how old you said the plants were, but if they don't start getting their normal green color back again, you could probably bump up the amount of N fertilizer you're feeding them until color levels back out. Just remember to be careful with any soluble fertilizers that you use, start with a very dilute amount, and work your way up until you see how much the plant can tolerate.

Take care. :jointsmile:

[sensilights]

Hey thanks again!


This isn't necessarily related but is it a bad thing if the first set with 1 blade and the second set with 3 blades yellow? If the rest of the plant is still beautifully green? Just noticed it while uh...surfing the net...this morning :P

[stickyicky07]

if you found those pics on the internet, how do you know the first 3 pics are the same plant????

[sensilights]

*ahem* trust me its the same plant :P

LOL, it's fairly common to see that in young plants, especially if they're in small containers. Generally when I see that - while surfing the web, that is ;) - it tells me that the seedlings have become a bit rootbound, and aren't able to uptake nutrients as efficiently. Once they've been put in larger pots, it generally clears right up, and kick-starts a growth spurt. If they aren't in need of a transplant, temperatures are in a good range, and the plant has more than 4 nodes, then a light feeding with a Nitrogen fertilizer should help.

Take care. :jointsmile:

[sensilights]

so if these...internet plants...were approx 8-12" tall and in a 4x4x4 pot would they need repotting? From what i've seen it doesn't seem to look like there are any roots showing on the bottom of the pot through the drain holes..also if the only thing on hand was a bit of miracle grow bloom booster 10-15-10 and that was dissolved in snow water at about 1/8 of the recommended dose could that solve the nitrogen need?

[Mr. Clandestine]

Sounds like they may be close to needing a transplant, but hard to say for sure. If when taken out of their pot, the roots have noticeably bundled at the bottom and all around the sides of the pot, it's probably about time. If there's still plenty of soil for the roots to grow into, move on to Plan B.

As for the MG, it sounds to have been made as a bloom booster, and while it will provide smaller amounts of Nitrogen, it will also offer a higher percentage of Phosphorus, which vegging plants don't need quite as much of. Fish emulsion (5-1-1) is very cheap and is great for a N boost in veg, and there are several chemical fertilizers that would do the trick. If possible, try to find a fertilizer that's got a higher N to P-K ratio for veg, and if it's absolutely necessary, use the 10-15-10 for flower. Even then, use sparingly, as MG ferts can be a little overbearing for these wonderful internet plants. :jointsmile:

4" cube pots are about a quart, and you need about a gallon for a foot tall plant. Pot up! :D
Don't use snow water; you need calcium! Same as rainwater... no minerals, and typically low pH. Did you know that you can have 'acid snow' too, just like acid rain? Unless you KNOW your tap water sucks, use that instead.

[Mr. Clandestine]

I never knew that! I always assumed that snow was much more pure than rain, I guess just for the sole reason that it was frozen. Of course, I don't live in a state that sees snow, so that explains my ignorance of the white stuff. Well damn Stinky, I knew you should never eat yellow snow... but I guess it would be a bad idea to eat ANY snow, eh?

[stinkyattic]

Hey, I watch out where the huskies go (or in my case the bullies) too... lol

I've actually done analytical chem on snow samples and found the same types of contam in it- nitric and sulfuric acid from exhaust/smoke/smog in the area that is the weather pattern source. In my area, our weather sweeps down from the Rust Belt region and our precip is acidic as a result.

That's good stuff to know, I'll be sure not to advise that anyone use rain OR snow water to feed their plants with. And I'll also be sure that if it ever does snow down here in my neck of the woods again, that I don't eat it anymore! :jointsmile:

[stinkyattic]

It's okay to eat. Unless it's yellow.
Around here, we have sugar-on-snow, which is maple syrup fresh outta the evaporator, drizzled on snow so it hardens into candy. Mmmm! I love New England!

[sensilights]

wow thanks guys for all the tidbits of info here...its starting to warm up enough i think whereever these internet plants are that whoever is growing them could probably run outside and use the 1 tap that isn't softened :D

Tomorrow is payday for said mythical person so maybe that person should run to a local nursery and pick up some fish emulsion :D

You guys are the best :D:thumbsup::jointsmile:

[sensilights]

interestingly enough the ph of melted snow is 6.6 compared to the soft water which was 7.2-7.4 dunno if that means anything but i found interesting lol

[stinkyattic]

Your melted snow isn't bad IF you add calmag plus. That will also bump the pH up just a hair. I'd choose it over the softened water personally. I assume you run a water softener because your tap water is leaving calcium scale on your fixtures?

[sensilights]

The softened water does tend to get the clothes and dishes cleaner and feels nice on the skin :P There is 1 tap though left unsoftened...its just outside through the snow lol

So apparently fish emulsion looks and smells like poo literally lol but within 12 hours of application turned light green leaves to dark green leaves I just may add it to my fertigator for my sprinkler system and make my grass pretty this spring :D

[stinkyattic]

Sounds like things are turning around. Fish emulsion is great but easy to OD on so as soon as the def symptoms clear up, I'd cut WAY back on it. Your lawn will love it though, lol! Grass needs a good deal of N. But phee eww.

[sensilights]

application was 1/32 tsp to .25L of water.


This mystery grower was thinking of adding it to all 3 plants again sometime this weekend after transplanting at a 1/8 tsp to .5L or so...would that be acceptable?


Also slightly off-topic here...i have a compost pile i've been working on in my backyard for a few years...at my office we have a lot of shredded paper, what i'm wondering is would that be a good additive to my compost? I'm gonna be adding some super manure *mix of chicken, duck, and donkey* to it this spring before i add it to the vegetable garden and was wondering if i might be able to recycle some of this shredded paper as well :D

[stinkyattic]

I've heard of people happily composting shredded paper. You'll probably want to look it up to see if you have to do anything special, but my guess is just watering, turning, allowing to heat up, and making sure that you have good microorganisms in there.
Donkey manure? :wtf: OMG I'm not sure if I even wanna know haha

[sensilights]

yeah they sell the chickens and ducks but i'm not real sure why the donkey is there lol
