What's new

when the first 2 non leaves of a seedling turn yellow

think cotyleons is what they're called..is it time to put them in full strength lc's mix with recipe #1?... i have them in plain lc's mix,with no fertilize..just peat,compost and manure,dolomite lime and perlite..they are skunk#1 and mandala mix,18 days old under fluoros.
 
You say you don't have any fertilizer in your starting pots, but then you say you have peat, compost and manure. Not that peat is a great nutrient source, it is just beginning to decompose when it's dug up...and your watering it.

I was watching Nat Geo on a nature area down around New Orleans, where the fresh water meets the Ocean. They were saying how CO2 levels have risen down there, because of Katrina. A lot of trees were knocked down so the peat bogs are being heated, causing a rapid decomposition.

Heat, bacteria and moisture will turn peat into nutrients but nothing quite like manure! I think your manure might be to strong, that maybe causing the yellowing or perhaps your over watering.

Try the infirmary, fill out the questioner as best as you can
 
guess you are not familiar with lc's mix..it has bone,blood,and kelp meal as a food source..i dont think there is anything wrong with my plants..just want to know when i should re-pot to full nutrients..

18 days, I would fert..

but to me the cots are not a sign, as they can yellow sooner or longer depending on conditions..

you can leave them in the pots and nute them if you want, or you can re-pot them into larger containers if you want

If youthink they need some thing to eat give them a EWC slurry. EWC does not burn and it will hold the plants until transplant.

i second the EWC slurry. unless they are getting rootbound then transplant up.

you all say just 18 days in the peat/perlite/EWC/dolo lime mix is all they need until they can be transplanted is full LC's mix w/ all nutrients?

This information is completely and totally anecdotal but it's been my experience that 'old seeds' will more often than not show the yellow deal that you're describing.

The last time that I bought seeds was over 21 years ago so all of my experience with germinating seeds has to do with the old stuff that I have.

I always figured that since they were old seeds that the yellow leaf deal was just part of the process, i.e. I never gave it much thought because generally the seedlings moved up and onward to a point where I felt that I could make an intelligent decision on whether or not to continue that genetic line.

If your starting in something like keg cups, it'll be a while before you'll be able to transplant them, otherwise when you goto pop them out, there won't be enough root development to hold the ball together (more then likely).

Granted, that all has to do with conditions and overall vigor. Of all the times I've used LC's mix, I tried to wait until I know they were ready to transplant before actually moving them to the mix that has the blood,bone,etc in it.

I second the EWC slurry mentioned above. It'll give them a nice boost without the worry of fucking em up.

Even if you see roots at the bottom of the container doesn't necessarly mean they need to be transplanted as the tap root grows like crack anyways, and that could be what you are seeing.

Top dress and water in with EWC is what I recommend, don't get in a hurry to give them the fert mix, some strains are slower to kick into there Veg stage.

On an additional note, there's too many variables in growing MJ that can lead a person to say "do this at this time exactly". What works for one grower, might not necessarly work for another. It's just a general guideline.

Let the plants tell you what they want, when they want it.

And don't worry too much about it, not giving them nutes at the earliest time they possibly want them isn't going to make them drop dead and die.

Hope that helps!

i appreciate everybodys help. because they had gotten droopy, i transplanted them from cups to square pots on the 3/26, and they're lookin better. was all kinds of roots circling the bottom of cups so i think they wre rootbound..the last container for these will be 1 gallon buckets and i'm gonna hold off as long as possible..this is my 1st experience with seeds and before i start any more i'm just tryin to find out what they do and or dont need..
 
one more question..compared to my northern light clones(4 wks old) which are green,the skunk#1 and mandala mix are as yellow as can be. is that normal or does it mean they need some nitrogen?

yellowing fans

yellowing fans

plants are 3-4 weeks into flower, large fans are turning yellow starting towards bottom of plant, seems early for the yellowing, best course of action?

The good thing about organics is the need to not flush at the end of the flowering cycle, because simply, you can't flush organics.

Though you want minimal nitrogen that far into flower, I feel your plants might be hindered by the lack of it at 3-4 weeks. If I were you I would do the same as above and hit them with a dose of EWC top dressings or slurry. That will be a quick absorbed nitrogen source for your plants, and shouldn't overwhelm them with it.

And, yes Cosmic, I would say you need some nitrogen, but, if your using LC's mix and your clones are in it, it should have plenty of what the plant needs in it. Did you moisten the mix first and let it sit a couple weeks?

If not, it's possible that the microorganisms haven't broken the blood meal down enough yet. I would just hit them with some EWC slurry which should kick start those micros into gear, and some molasses wouldn't hurt to feed the micros.

Also Cosmic,

If your referring to the same plants you just recently transplanted, they should start to green up in a few days once the roots get established into the new mix. You transplanted into the veg/flowering LC mix correct?

no,i put them into bigger containers but they're still in peat,compost and manure,dolomite lime and perlite..is it time to put them in the veg/flowering lc's mix?...i've never grown from seeds or sativas so i'm in new territory..

yes defiantly put them in the full mix. as they are big enough and they need all those extra nutrients now.
