Early concerns!!!

[sahima]

Hello!!! Here are some young 19 days old plants. As you can see they are very stretchy and slim, and if you look closer you will see some yellowing at the first pair of leaves (1st photo), and at the newer growth a slight yellowing at the perimeter of the fingers.The cotyledons are already dead. Sorry about the quality of the pics,i am using a crappy cam.





The seedlings are under 4x18W floros not more than 4 cm away. The soil is biobizz allmix, no nutes added.The pots are something like 1L.Medium watering every 2-3 days when the soil is dry.The temps are fine, 25-28c. The little plants are now developing the 5th node.
Don't know nothing about the p.h of the water, but the soil p.h must be fine as a biobizz product.
This is some friends grow and i would like any help or advice. The strain is NLxhaze from femaleseeds.nl.
I don't have an internet connection, so forgive my absence for a while!!!

Thanks in advance...

Forget to mention that humidity is now 40% Rh, and the previous 2-3 days was as low as 30%.No fan in the growroom(cold weather to use one) The first symptoms started 3 days ago. Not that big problems but aware for their future.You know, every parent wants the best for his child ...

I would say they're starting to get hungry. What do you have to feed them? Any fish emulsion? I'd give them a weak feeding the next watering.

Hi and thanks for stopping by, so you think that it is time for nutes? I know that all mix is pretty ''hot'' and i was thinking that it would be enought nutritients in there(no serious run off from the waterings untill now) until the first transplant!!! But yes, next time i am thinking to give a small 1/3 dose of biogrow(biobizz).

 

[sirgrassalot]

It looks like they survived the hot mix when they were tiny. The cotyledons do die. If you're thinking of transplanting will you be using the hot mix. I would watch making both available to the plant. If I were to transplant into regular potting soil I would have prepared the larger pot with a weak solution of fish & water than dump the plant into that at this stage. So I'd watch using both. I don't know what's in the mix.

I'm a little confused on the hot soil?

"The soil is biobizz allmix, no nutes added."

Ever think about tying those plants over?

Those leaves always end up dying, right now I would not feed them plants, the fan leaves are not being affected, so feeding them when they are in all mix is asking for trouble.

Also why would he need to tie his plants over????


In about a week to week 1/2 you can feed them a small dose, those leaves always die on the plants they are pretty much food after cotyldons fall off, it's a small storage the plant uses and drops when it's not needed. So I would not feed right now imo.
All mix is a hot mixture and you are lucky they are not showing any signs of tip burn, your strain must be able to take the hot mixture, not all strains can take that mixture at this age and younger.
Were they put in this mixture since seed?



The plant that is bending inwards, you need more light; the reason why it's bending is because the plant is trying to get the light, fluros are only good at very close range and the range the plant is at is enough to make the plant bend towards the light.

Add some compact fluros if you can, they need more light, that is another reason why they are a little stretchy too, the lights are not being kept close enough.

You missed my second post. It helps to read everything before attacking my information, again.

 

[MynameStitch]

Um, those are not cotyledons, those are the first leaves that come out AFTER the cotyledons. If I were attacking you, you would know it. I may be blunt with words, but I am not attacking you and I am sorry if I come across as I am. I am just pointing out things that I think is wrong and I have the right to do so, just like anyone else does.I am not right 100% of the time no one is.
I did read your post, I read everyones posts. Not to mention why would you use fish emulsion to solve a problem that is not occurring? the plant naturally kills off those lower leaves, because the leaves are not needed.
He feeds those plants anything and there will be a bigger problem. Not to mention when you have a nitrogen deficiency when the plant is hungry, chances are if they are hungry there is going to be other problems following, fish emulsion should be used to fix flowering issues, if you have a nitrogen deficiency in veg, then you are either having a lockout issue or your clearly not feeding enough and if your not feeding enough, fish emulsion will not be a complete feed.

When you say those what exactly do you mean? Care to crop the image?

 

[MynameStitch]

Those being the yellowing leaves with some green that have a single blade I don't need to crop the image if you can't see it then not my problem. You know what I am talking about too. SO are you telling me those are cotyledons?

Also; see how the top part of the plant is yellowing around the edges? that is called an early sign to a zinc lockout from his mixture being too hot, so a flush is needed to fix it, so again are you telling me his plants are hungry?

SHamina: Your plants are going to start showing worse problems, since they have been in this mixture for a little bit, the amount of phosphorus in the mixture is causing the plant to start to lockout zinc, you should flush the plant out with about 1 1/2 gallons of water, the yellowing edges around the top part of the plant is not normal and if it's not fixed it will end up making the veins turn yellow too.

I try not to be so cryptic when helping the poster.

REad the thread posters comments:

He already knows the cotyledons are dead: HE is asking about the first set of leaves NOT the cotyledons.

This right here is a perfect example of why I say you are talking about other things that is not even the problem and the cause of why I point at your posts.

 

[sirgrassalot]

The cotyledons are already dead.

LMAO right he didn't ask.

 

[sirgrassalot]

Well fear not I wasn't listening to you.

 

[MynameStitch]

I am refearing to your post, I know he did not ASK about them being dead,I can read!!! but my post was aimed at YOU! See how things just go right over your head? You based your advice saying they needed fed only because the leaves were yellow, he listed no pH run off no nothing.... He even said it right here!

Don't know nothing about the p.h of the water, but the soil p.h must be fine as a biobizz product.

he could have had a pH problem and using more food would have caused a worse problem! See what you get when you DON'T ask for details! So if the thread poster did take your advice he would have come back here with worse plants and now you see why I critique at some of your posts! You leave out details and you don't ask for them and post mis information. Another perfect example!

It looks like they survived the hot mix when they were tiny. The cotyledons do die. If you're thinking of transplanting will you be using the hot mix. I would watch making both available to the plant. If I were to transplant into regular potting soil I would have prepared the larger pot with a weak solution of fish & water than dump the plant into that at this stage. So I'd watch using both.

[sirgrassalot]

You're not making any sense.

 

[MynameStitch]

Dude I am not going to explain this anymore after this since everything goes over your head and you don't understand some of the stuff people type I will put it in easier terms for you!! You said for him to feed correct? But he did not list any PH run off!!! If his soil pH was off causing it to look like it was hungry and he fed per your advice he would have more problems, thus is an example of what I said about knowing details before you give an answer and to why I told you stop removing details when you ask questions. Also, I don't get my post count up by posting misinformation and just telling someone what is wrong without getting the full details like you, mine are full of good growing information and information that is passed on to peeps. You on the other hand get your post count up by posting small sentences and telling someone a problem they are having that is not true!

Hi Stitch...

Hi Stitch...

...I haven't done anything this 2 days, and the problem spead. As you can see from the photos the yellowing progressing up to the plants. The second pair of leaves yellowing now and the first one is completely yellow. There are a few brown spots too, not at the edges of the leaves. And at the top leaves the problem remains like a zinc deficiency. All the plants except of a younger one have exactly the same symptoms.

It is almost time for the next watering, i am going to flush the plants as you suggest. Should i be worry about overwatering issues after flushing a small plant with 2-3 litres water(1+1/2 gallon?) ? Never done it before and i am little worried.

Strange but i used the same recipe for my past grows and it was fine. Even the guy at the growshop told me that Allmix is o.k for seedlings. Must mention that the grow started with no problems with very healthy seedlings. The younger one you can see at the last photo is o.k, should i flush it too?
Thanks for the help!

They look like they need some Mg. I'd transplant into your mix with some Epsom salt in the soil or give a light spraying with some Epsom mixed with water. They did survive the all mix when they were tiny. They're not tiny now.

 

[MynameStitch]

It's not magnesium, he has a lockout issue zinc is being locked out from the soil being too hot, you have too much phosphorus in the mixture, flush your plants out. Magnesium does not start like that. The mixture is too hot and the strain is getting tired of it. Flush your plants out with around 2 gallons of water each. For the smaller plant put a fan on them to help dry out the soil.

I would not transplant them, they have not rooted up the pot yet, so you risk ripping roots and dropping soil which causes the roots to tear and you don't want that./

Dude, those hydro guys don't know shit, read my sig for proof, it happens time and time again.

All mix should never be used for seedlings, you always have a chance risking them to burn.
Flush each plant out with 2 gallons of water.
If you added magnesium to the mixture and did not flush you would have problems.
