What Am I Doing Wrong (Seedlings faded & dull) ???

[NorthofEngland]

These seeds were germinated on March 28th
and placed in rockwool on March 31st.
They were originally in propagator but,
on advice received, removed.
They dried out too easily so I returned them to prop.

The leaves appear burnt - but they only get EC0.6 feed.

Browning, fading and lifeless.
Distinct lack of growth....

Temps between 70 and 80
Very low humidity - outside prop
60-80% - inside prop.

Any help appreciated
(these are the first seeds I've ever tried to grow
and I've already killed my one and only BLUE O.G. !).

They are:
Front 2 - (left to right)
Dinafem CHEESE
T H Seeds CRITICAL HOG
Back 3 - (left to right)
Strain Hunters Seeds FLOWERBOMB KUSH
H.S.O. GREEN CRACK and
G13 Labs SUGAR BLACK ROSE.

All 5 are FEMINIZED.

I hoped to attempt my first MAINLINE
but I'll settle for just keeping them alive.

Wait tell like week 2 1/2 or 3 to feed those are really small and stunted I would trash them and start over, start in soil a lot easier more room for error so you can get the hang of it down

I grow in clay pebbles (hydroton) and have everything for this medium, so growing in soil isn't an option.
I want to know what I've done wrong and learn from it, so I don't see the benefit of simply chucking them an starting again....
I have 17 Skunk#1 on Day 50 of Flower
and 20 cuttings rooting in the prop.

These seeds are just a side project but I'm eager to learn how to grow from seed.

lockout...your killing them with kindness. So you dont ever grow from seed? Next time ZERO nutes until there couple inches tall. Id just run straight water on them and see if they will recover.

 

[tip top toker]

As above, why on earth are you giving them nutes.

My tap water has EC0.5
is this too high...?

 

[booms111]

Is your tap water from a well or city water? thats like 250ppm so id imagine its well water. Id say it would be ok. What ferts were you using to raise to .6? My well tap water is 200ppm and i dont have issues.

It's tap water - my supplier told me that it's pumped from 'chalk aquifers'.
Usually I mix 60% rain with 40% tap water to get a base of EC0.3/pH 6.9
I then use Canna Aqua Vega A&B, Canna Rhizotonic
from the 3rd week of veg I use Canna Zym
from Week 5 of bud I use Canna PK13/14 and Canna Mono Magnesium
and Essentials pH Down.

IMO all that algae on your blocks could be your issue.

Even though you're feeding the seedlings the algae is what's using it to grow by the looks of it.

You need to get the blocks covered from the light.

You could save these plants but I'd recommend a bleach dip to try and kill the algae.

10% bleach solution should do the trick.

Dip your blocks into the solution for about a minute.

Then get them covered.

IMO just use your 60/40 rain and tap for now until you can get them to bounce back.

The algae growth tells me your cubes are a bit too moist, they should be damp but never dripping with water. I would definitely stop feeding them as well...

 

[jartlow]

Brown tips means overwatering. Also what lights are you using.. too strong and they'll cook em!

WHAT BLEACH....????
Normal household bleach (10%) ?

I had them under 2 x 55w T5HO (blue spectrum).
Today I put them under 600w MH - but it's a good 5 ft above them.

I worried they were over wet BUT I lost my Blue OG (and nearly lost my Cheese) when the cubes dried out....!
I think I need to learn a way to start seeds/seedlings that doesn't involve rockwool.

 

[jondamon]

Yes just standard bleach.

No perfumes or added extras.

Cheap as chips bleach.


I've dipped whole plants before now just to be rid of pests.

[NorthofEngland]

They've been squeezed. Dipped in bleach and squeezed. Dipped, soaked and squeezed.
Dipped in purewater and squeezed (twice).
Then re-potted.

But I still need to know what I did wrong....?

 

[DroidBoy]

seems from reading this post 1 of the things u did wrong is gave them nutes way too early

 

[vostok]

I once heard that when you buy seeds they come with their own FREE food or nute supply good for 2-3 weeks, you obviously didn't take advantage of that deal ....and fed them yourself...? good for you, but you may have overdone it, time to start again...?

Only true if going into a slightly fert'd seedling soil.

Try to pop a seed in rockwool and see how long plain water will get the plant through.

What happens is that after only a few days the cotyledons will yellow then the single blade leaf will yellow as the seedling grows each lower leaf set will give up its stored reserve to grow the upper plant.

I only gave them EC0.6 solution.
0.1 stronger than my tap water.
The cotyledons did turn brown, then the 1 leaf, then the 3.....
Now the TINY 5 leaf sets are healthy looking.

This is why I PM Jondamon for clarification about virtually everything.

So many people give advice without really knowing the subject.

In the last few threads Vostok has given completely incorrect advice two or three times.

North i think i can help.
rock wool: a 1.5x1.5 cube weighs 5g dry.
It should only weigh 20-25g wet.
I learned this from al b fuct (great guy-great threads). I still have the occasional problem doing seeds in wool but that is cause i forget to get out the salad spinner and get the wool to the right weight. Also, once wool is squeezed it will never be the same again.

Also, i found household rh a problem: under 50% seems to be a problem in the first few weeks.

finally, i typically take a seedling with a second set of leaves, ferts at 1000ppm, 1000w at 36"(90cm), rh ~40-60% and watch them GO.
seeds are both an art and a science imho
it is much easier to start them in peat or a highly aerated soil. Having said that i have seen strains that love peat and don't do as well in wool. vice versa as well

Best of luck

Perhaps if you stuck to Pm-ing just one member of RIU.org, you might not be in such a mess?
and not receive so many conflicting advices, still further proof that a high post count here or any site, don't necessary make the horticulturist ...no?
