Yellowing question

[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:

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:

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!
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.
