Trouble: Young seedling in coco

Hi all,

this is my second grow. First was a real pleasure last year with coco :)

So started up with same setting, only thing, added mylar to walls this year and bought different coco bricks.

The setup: closet 4 x 2 x 6 foot, 210w CFL total 1-2 inch away, circulating fan on seedlings, temp 78-79F, no feeding only regular tap water (ph around 8 - will bring PH to 5.8 when start feeding), 3 sativa dominant seedlings 5 days old in 1.5 gallon pots.

The Problem: weird leaf growth (very upwards) and curling, also very slow growth, now light-pale spots on first forming leaves. To me seems like nute burn, but thats impossible as coco has zero nutrition and not feeding yet...So got little panicked today and flushed them all with PH-d water, lots of dark brown runoff came out....Any ideas?

im sure they are, but no plant is perfect and over mothering them is a sure step towards failure, as long as its growing i wouldn't really worry looks healthy enough to me ^^ yeah what that guy said maybe back the light up an inch or 2
 
what ive learned from my first grow... is that dont kill them with kindness let them do there own thing!!!!!! cause i would always freak out if i saw something i thought wasnt right .... and well 3 weeks after veg i pulled her cause i killed her with kindness...... too muhc attention too much stress on her and bam troubled plant :(
 
Why does everyone flush first and ask questions later?

That light is WAY too close. Let the thing grow some leaves at least ; )

And I would get the fan off the plants. Its way too much and It shouldn't blow directly on them. Those are barely seedlings. More like sprouts. Treat them like babies and stop hammering them with blinding light, heat and gale force winds.

I laughed my ass off when I read your line and I haven't even had my coffee yet.....:mrgreen:
 
well after yesterdays flush things dont look much better. Still yellowing and one seedling got its head down, so had to tie her... Have now shot down my fan and moved lights about 4 inch away.

Doesnt look good, I`ll wait for another few days and if no change I`m afraid abort :sad:

Yeah keep the light several inches away for now and no direct breeze. Keep the media moist but not saturated at all times, and they should do fine.

What kind of coco coir are you using/where did you get it from? Most coco coir for horticultural purposes comes thoroughly rinsed to remove any salt which accumulated in the material. However, some coir products might not have been prepped as extensively and might still have salt in them.
 
Killed 2 of them today as they were crisp and yellow...Thought I had learned more from my last grow...well it`s my tragedy. Kept one as it was the only one showing some green left. Will keep it under 2 23w cfl until I see some growth and trying to keep it moist. Still have not watered since my "emergency flush" 3 days ago.
And be waiting for my chance of getting new seeds to start over where I left....lesson learned I hope
 
get some soil and mix it with your coco budds.
soil is way more forgiving and has a bit of food in it for the seedlings as well.
if i were you i would just get rid of the coco and use soil and perlite.
i guarantee you will have better results :)
you are still new to this so why not use something for beginners?
 
hi guys,

little update/advice request on this. So I saved one girl from the heat/fan disaster I had. She is Amnesia Lemon and atleast she`s alive. But she is a little dwarf (1.5 inch tall) and growing very slowly. She is 13 days old today.
Did let pot dry out for 2 days and watered her again today with little Coco A+B (0.2ml per liter of PH`d water). Well the question is I guess: Does this look hopeless and kill her, save some money and energy until new seeds? Or any hope left? Any experience with such slow seedling anyone?

Until it's dead, it'll keep trying to survive. Once it stacks on a few leaves you'd be surprised how quickly it can take off.

but

a) the medium has looked drenched in every photo you've posted thus far: let it dry out a bit more between drenchings. Overwatering not only creates an environment for bacteria and rotting roots, it also encourages lazy plants. Seedlings of all species take off faster when they have to stretch their roots to seek-out moisture, but I also know what coir is like: it's either sopping wet or dust dry. Which leads me to

b) Coir is a dreadful medium to use. Very little air-pockets in the stuff, and well. I planted about 50 mixed vegetable seedlings this year in coir, and apart from the soggy/dry nightmare, only about 3 seeds popped. Coor is sposed to be a bit on the acid side for seedlings, so I advise 2 parts plain seed-raising mix or potting mix with 1 part perlite.

I'd just leave the plant and give it a chance, a fortnight isnt long for a stunted plant, and when ot recovers, it'll pile-on the growth-rate fine. Besides, you planted the poor thing, and it's doing it's best to survice, so give it a chance. Next time, ditch the coir and use potting mix/perlite. More air gets around the roots, .. Just works better.
