seedlings not growing..

[Mike Myers]

Here's a pic of the one I up-potted a few days ago, spent way to much time in that dixie cup.

Roots don't need to spread and grow when the soil is soaked, use half the water you think you need,,,the plant will tell you when she's thirsty.

BTW:You never answered the PH & temperature question.

I think it is best for the stability in the root zone to water thoroughly and not water too often. Depending on the medium. Coco coir every other day or fewer, soilless mix twice a week as a guideline.

I grew autoflowers in a 2.5 gallon pots with reservoir, woodchip mulch that keeps the soil moist, with a supersoil type mix for nutrients, from seed, and just watered/fed with a high P/K solution once, planted, and watered again a week later. Which is the way to go if you plant in a large pot.

Also, seedlings like air moisture more than moisture in the medium. In fact if you keep humidity higher, you can and should water less.

Hey Bwanabud.. temp been from 65 to75 and 80 sometimes..ph sittin around 6.8 according to ph meter and test strips..my tap water runs about 7.4 but have been using distilled water..pretty cold out ...right now the temp is 63 and rh at 73%..had humidity up most of time...one reason I think the soil never did dry out any.. one read said that seedling dont need the higher humidity though..thats more for clones...so I have let it drop some..and as far as flushing and drying.. can you actually just take the plant, and literally just flush all soil off of roots...that sounds kinda scary...

 

[rasta man]

In a light mix like that probably no more than a day or two.... 12-18 hours in water.

If your light feeder isn't looking right.... don't wait.... flush her with clear water NOW. Young roots like that will die.

Don't love them to death!

If you just Have to do Something,,,, check the PH of your water.... then the PH of the run off water...

Oh, and try NOT to do what I did....experimenting is costly, if you are needing productivity.... I don't care, so I experimented frequently.

FYI on the peanut butter jars. I have plants that are approaching 2' tall.... with an airstone in each one....

Downside is at this size, they run OUT of water inside of 24 hours... doesn't seem to bother them though.

Had 8-9' plants in the GH last summer... in 5 gal. Homers,,, they were on a reservoir and a float valve to keep the water levels up in all of them. Have to watch your water PH, especially closer to harvest. I've had an AK47 that made acid 2 weeks before harvest.

That being said I'm guessing that may happen in Coco, and dirt as well. I expect that most gardeners don't check the PH of their substrate EVER.

and when you say your plant made acid...what does that mean?probably not that it was so good it made you trip..

Rasta;
After I hit the send button,,, I'm thinking, maybe there Are traces of manganese it too. lol

Freshly Baked this a.m....

P.S. For what it's not worth, I normally used 3 gals of water to flush a 3 gal pot. Unless I'm needing to up-pot anyway.

Stoner wondering; What if you added aeration to the soil/dirt/coco? Would it still be overwatered?

In DWC, the roots are Always sitting in pure water. Hmmmmm

But you were right 2Legal... I was mixed up not only in my words but my intentions..I had , along the line somewhere , got the two mixed up thinkin they were the same, so thanks for pointing it out... still not sure of good manganese additive..I have bought some super thrive but it does not say much about the ingredients..smells strong..little bit on finger really really stinks..

 

[rasta man]

Plants still growing but slow..have decided against bringing in clones and trying that..but I have some bagseed from smoke that friend has grown same strain for almost 30 years...hoping it turns out well..used good reading glasses and magnifying glass to check end of seeds for the little volcanos..hoping to increase rate of females..have read about it , plus the guy the seed came from said he uses that technique because he got tired of raising males.. apparently he has good success with it...

 

[rasta man]

And I finally see the difference in vermiculite and perlite..perlite from now on.. verm. might have its place but it seems to hold too much water

 

[Bwanabud]

A minimum of 50% Perlite, you have to have great drainage. Then if a flush is needed it drains quickly, and the pot doesn't sit wet...leading to overwater/saturated roots.

63 deg is far too cold for a 2" baby, has to stay 72-75 to allow her to demand water/photosynthesis to take place. She's been thru a lot of stress, let her dry out, water lightly, quit poking the dog with a stick

Seedlings don't need nutes & lots of attention, just let her be...she knows what to do.

 

[rasta man]

yes on the perlite... people tellin me to flush.. aint no way to flush my media..would take two weeks for it to dry out...thats why Im likin the idea of the perlite since Im gotten use to it.. especially the chunkier kind .. some of it seems too small and doesnt work well..bu this last kind I just got is nice and big...good for drainage, huh,,thast what Im lackin ,,for one thing.. been pokin holes in media tryin to get air down in roots and to get it to dry out..seems to be working..

 

[Bwanabud]

For them to be 3 1/2 weeks old & 2" tall...definitely cold or too wet...or both. All of my babies are 12-14" tall at that age, 10 different strains. She should be visibly growing each day, and I'd be trimming/fimming the shit out of her by now.

 

[rasta man]

gotta be the water...had plenty of warmth..light too close too from what ive read on leds..pretty discouraging for sure..use to grown 12 footers outside years ago..now cant get em to grow a foot..

 

[sawney beane]

Hi rasta man you're getting good advice here BUT there's a repeated bit you're not taking in too well- LET THEM BE
I recommend you stick them under your light and close up shop and don't even open to check for 3 days (@ least)
Then when you check there will be a clearer sign if & what might be needed.

If were me and they are as wet as it looks I wouldn't even check for a week

Totally understand that u feel u have to do something so do the best u can for them by letting them recover first

Take it easy man you'll get there

Point taken sawney..worse possible thing for me not workin..soon as it warms up a bit I can git back outside and get away ... jus let em b

I just think you're "trying" to hard friend, over loving is the number 1 cause of problems/failure. She got too wet at the beginning, then nute issues, then cold/cold root zone, then, then, then

If she won't dry out, and the soil is too damp...she probably doesn't have enough root mass to deal with the water saturation. You either dry her out with consistent warm climate control, or re-pot her in new DRY soil/media.

 

[rasta man]

I had already had her out before our last conversation.. but I decided shes either gonna die or not be worth keepin around anyway so I pulled her out and laid her in some ph proper water with a bit of the superthrive...,soaked her in that for bout an hour...put her in some fresh medium...dang root is long...lot longer than the cup...trouble is werent many laterals comin off main tap...or so small they tore off.. anyway, thats what I did and now Im gonna just leave em be...except for checking for new shoots poppin on newly planted beans..

 

[sawney beane]

Yip over lovin & I'm sure Idve did same if even half of products were so available

Maybe could use some cheap flouros for a bit till recovered enough for the led
? Tho I've no idea about led but thats what I'd do, that & leave them be for couple days ;-)

 

[Bwanabud]

put some holes in the bottom of that cup for drainage & air.

 

[rasta man]

problem resolved... I feel like 98% sure that my problem now is rust..the spots on the leaves... and it all makes sense from a post I read over on 420..I kept the place humid cause I had heard thats what the seedlings like...and I also thought, dont really need a fan on till they get a little bigger since they are not lanky at all...
and I did not see a reason to run the exhaust fan since there was no heat buildup...man.... what a recipe for disaster....
started off by over watering as mentioned by several of the posts..
no circulation with a fan..
no ventilation or seldom
high humidity levels...
apparently a perfect recipe for Rust...not the kind in your pipes.. its a spore or something.. maybe a mold spore created with the high temps, high humidity and no ventilation/circulation..just thought I would pass along that info ...until I get some copper sulfate and lime , I have removed all infected leaves.. poor things..and sprayed with a solution of oil,vinegar,baking soda and dish liquid..fingers crossed..
and have plenty of holes in cups,Bwanabud..another batch on the way ..hope to have the rust under control by time they come up

 

[Bwanabud]

Remember that 80% of all moisture taken in by the plant occurs in the leaves, when you start spraying "stuff" on them the PH imbalance can cause serious problems....normally mix your foliage spray, then check the PH...Most rust issues I've ever encountered came from water PH issues...just saying Rasta
