Yellow> brown leafs on young plants

[dvine]

Ok here we go...
There plants are 17 days old, its a total of 16 (not shown) all of them have used the same water (rainwater), they have not been waterd at the same time, only when needed. I belive there is something (missing?) in the soil that harms them or that they need but dont get but i cant figure out what it is so i can correct it. The drainwater is about 6.7 so there should not be any ph problems.

 

[Guest]

well if its not ph, it looks like your soil might be too hot for them

i know what happening. you might be a little confused about fertilizer regimines. young plants do want food not just water. water is okay for germinatin. but once the cotllyedons appear they should get 1/3 to 1/2 strength veg food

actually thats still too early and the concentrations are still too strong, i know you are trying to help but that info is a bit off

Is it possible to get my plats growing good with only water in the grow phase?
Do i have to add nutrients into the water when i water (start mixing nutrients in water when they get there first 2 pointy leafs)?

 

[Guest]

water is good until like the 4th or 5th nodes appear, then do a light feeding 1/4 to 1/3 strength and adjust ph accordingly

 

[dvine]

but in this case i don't even get to that stage :/ i have only been watering with water and they end up like this. it started to show about 4-5 days ago and the problem is rapidly growing, alot faster then the plant it self.

When you guys says "to hot", do you mean its to much nutrients in the soil at this current stage? Should i try and go with more nutrient less soil?

 

[Guest]

Fried,you would only need fertilizer if that medium was inert like vermiculite.Most commercial soil doesn't need food for at least a month. Damn good example of too much care.

 

[Guest]

because your soil is probably "hot" meaning it already has nutes in it and they are too strong for your young plants

Ok so basicly i nutrient burn my plant. So to fix this problem i basicly needs to start over with a less "hot" soilmix.
How about i go with this soil and insted of having 30% perlite (currently 30% perlit and 70% soil) i make it 60-70% perlite. That would make the soilmix alot less hot, would it not ?

 

[Guest]

you could just flush (dump several gallons of water through the soil) or transplant into a different soil mix, but i would not just add a bunch of perlite it will change the water and air retention properties as 60-70% perlite is almost a soil-less mix

 

[dvine]

hm.. well that would only mean i have to water it alot more...
Ok i can always start with a new try, I have somewhere around 3000 seeds I can afford t fail a few more times

Ok this time im gonna try and use a soil thats adapted for cutuars and seeds.

How big pot do i need before i dare to try and use my current soil? Are 0.5L enoght or do i need around 1L ?

 

[Guest]

you could save these plants but they are set back for sure. I would start over.

 

[Guest]

you should use that hot soil to transplant into, after your plants are bigger their size and rootball will determine what size pot they should go into.

the soil for cuttings and seeds should be fine as soon as you transplant those burnt bitches into it. and no adding nutes for a while

 

[Guest]

There is lots of bagged soil that will grow seedlings. Diluting the FF would have been OK.Mix it with peat vermiculite ect....lots of soil recipies in posts of soil mix

Do you also belive its a nutrient burn?

Here is what the soil contains (swedish but you should understand anyways).

Here is what the soil im gonna use contains (for catuars and seeds it says)

Should i add perlite to this mix as well or should i just go with it just as it is?

 

[dvine]

Did the fast response ppl go to sleap now? =(

 

[Guest]

it looks a bit better, so its worth a try if you are wanting to save those plants you have, but as octodiem said it might be better to start over

 

[dvine]

How can i tell when its time to give em the real soil?

 

[Guest]

if you put them in the seedling mix now, then i would say that the next container you put them in can have that hot soil
