two seedling with problems?

[kbc2007]

Only these two (two at the top) are having some problems, so I'm not sure what's going on. Others are fine (like the one at the bottom of the pic).
I'm concerned about the wilting leaves, brown spots (top left plant) and the dry/brown bottom leaves on the top right one.
I'm using tap water that's been sitting for a few days.
I think I'm going to repot them and start using distilled water.
Here are the details...

1. Soil, soilless, hydro?- soil
2. pH of medium?- unsure but all other plants are healthy
3. Medium is made of?- soil, perlite, vermiculite
4. Room temp at plant height?- 66-67F day, 59F night
5. Age of plants?- two weeks
6. What nutes, dosages, and frequency?- none yet
7. Size lamp?- 6 26w daylight clf's
8. Light cycle. 24/0,, 18/6,, 12/12?- 18/6
9. In light cycle how long?- two weeks
10. Is lamp air cooled?- yes
11. Sat dom or indica dom?- indica
12. Magnesium is supplied by?- ?
13. Pests?- no
14. pH run off?- no

Thanks for any help.

I have done the same thing. Its over feeding them.

You may not be mixing a strong liquid food for them, but your soil has some food in it.

I was using ff and organic soil and liquid karma, thinking I cant hurt my plants cause its organic.

I had no idea how much food was in the soil, it was burning them because I was feeding weak nute solution thinking it was fine.

Flush the soil, and dont water them till they are alot lighter to lift than after you water them.

Flush them again, I did 2 good flushs that gave me runnof, it was clear the 3rd time I waterd them, and they are doing great now.

The better your soil drains, the better the flush will work, instead of just water logging a small root system. These plants died, I almost did it again to 2nd round of crop, but with stich help, I labeled the problem, and fixed it from there. Now they are better, waiting till I get a bit further to start thread. TOoo MUch. FooD.

I see no drainage holes in those cups and the temperatures are quite low. The range of 65-68 night and 68-75 day is more what you are looking for. Cold temps combined with poor drainage will give you problems, and from those pics, it looks like that is your main issue. The last piece of the puzzle is that if your soil is too acidic, the cold wet conditions will affect the plants in an even harsher way.
They are also a bit low in the cups... can you slice off a centimeter or so around the rim to improve air flow and get those plants transpiring more freely? And get some good holes around the bottom rim of the cups.

A pH runoff test would be good too if you have the means.
Edit: switching to distilled water isn't the answer unless you have a compelling reason not to trust your tap water. Tap water supplies Ca and Mg to your plants and the CaCO3 helps to keep the soil acidity under control.

 

[kbc2007]

Ok, thanks for the advice.
Just to clarify, the soil is pro-mix and I've used no ferts so far.
There are some drainage holes at the bottom of the cups.
Oh, and I'm working on fixing the temp. problem.
Thanks again!

 

[stinkyattic]

I'd increase drainage. You know how if you flip the cups over they have a little ridge around the bottom? I like to cut chunks out of the ridge itself to guarantee there is nothing restricting drainage.
Pro-mix will indeed drop in pH over time so be sure to get a test kit.

Ya, like stinky has said, looks to be a pH problem. Also the temp problem has to be fixed, seedlings can't live in temps like this. When the temps get cold you have a slow metabolizing plant that slows it's nutrient absorption down, not only does it slow down, but it also can lock out nutrients, phosphorus being the biggest one that is poorly absorbed in cold temps.

for 2 weeks of age they should be a little bigger and have at least one more set of leaves on them.

Edit: switching to distilled water isn't the answer unless you have a compelling reason not to trust your tap water. Tap water supplies Ca and Mg to your plants and the CaCO3 helps to keep the soil acidity under control.

This is solid advice stinky has given, I almost tell everyone never to use RO or dstilled water for seedlings, the much needed micronutrients help the growth with the plant that is crucial for it to get a good strong start. Distilled has nothing in it, it's just h202.

So unless your PPM's out of the tap is 250 or more you should get a water filter to try to clean it up a bit.

 

[kbc2007]

So i think it was drainage (and probably the temps).
I transplanted them to store bought 6" pots and when I did I noticed some of the roots had "white Fur" on them. I hope this goes away.
I also just moved them to a warmer place.

 

[stinkyattic]

White fur is a GOOD thing... it's the tiny hairs that grow on healthy roots. If the 'fur' is brown, start worrying!
Just FYI if the pots you bought came with pre-attached drip trays, drainage problems are still likely and you'll have to remove the trays.

 

[kbc2007]

Ok, thanks guys.
I'll let you know how it goes.

 

[MynameStitch]

Ya, like stinky has said

Let us know how things go!

As for delta_9, ignore the dude, he has no idea what he is talking about and is being a troll, so remember kids, don't feed the trolls!

 

[Stoned Cold]

you seem to want a pissing match & though I bet I'll win (I play dirty) that's not what I'm here for so check the attitude @ the door.

Yeah, you can hang it right on that rack, next to delta9s respect!


(Oops, I didnt mean to feed the troll!)


I'm sure ICmag is happy to have a member who admittedly plays dirty.
Are you an informant of some sort? Personally I dont care, my grow is gone, however, I'm sure NOBODY wants advice from a rat bastard!

Go see a therapist.

 

[MynameStitch]

Haha, stoned you are one funny person!

REmember now save your quarter and feed some other animals!

Remember no animals were harmed in the typing of this post!

 

[kbc2007]

Update,
I replanted them two days ago into bigger containers and into this mix...
2 parts Promix
1 part Perlite
1 part Vermiculite.
2 tbsp per gallon - Bone Meal
1 tbsp per gallon - Blood Meal
1 tbsp per gallon - Dolimite Lime

I've also warmed things up.
Tested the Ph and things look good at 6.5.

They're really looking bigger and better.
Thanks!

 

[HeadyPete]

Of course they are, because science trumps promix advertising and stubborn trolls who admit they are only here to cause shit.

Water and dirt splashed on them....hahahahahaha!

 

[MynameStitch]

Delta loves to delete his posts "how amusing"

 

[HeadyPete]

Deleted his valued and important advice? Say it ain't so....such conviction....

Well thankfully we are now free of that garbage....ugh...I need a shower after that.

 

[MynameStitch]

Yup, feel good to get rid of dirt lol

Good thing things are looking better, they look a little happier now

female preflower!

female preflower!

Just an update.
Of the 4 plants I had 1 turned out to be a female, take a look at the preflower picture.
The 3 males were killed (sorry guys).
So I've got 1 nice female plant still in veg right now...that's fine with me!

 

[sirgrassalot]

I usually plant the males at my local police department. LoL Were your plants touching each other during veg? That'll lead to more males.

This is a wind up ?
