Compost to hot

username1234567 · Feb 10, 2013

i have got some b&q own brand compost, i only started 1 seedling to see how it goes

turns out the compost is to hot ( baby leaves going brown, and half of the first true leaves are brown ) ( its only just started to grow it's 2nd pair )

My question is - Would a flush of the compost get out all the nutes? and make it liveable for future seedlings ( got 2 germing now )

If so, how much of a flush would it take? 4 times the pot size?

thanks.

I know getting some diffrent soil would be best, but not possible for me atm

Next time read the bag.

Start over in soil without nutes.

It says its multi purpose. for adult plants, seedlings, and clones

You don't start seedlings in nuted soil. Period.

I imagine the instructions tell you to mix the compost in with existing soil. and then gives measurements to an outdoor garden.

Knew i was being stupid, i will get some without nutes, and see if my orginal burnt one survives. but my ones germing now will get the soil in time.

Thanks Flaming!

am i right in thinking a seedling has enough nutes by its self until baby leaves die off?

First week and half to two weeks above ground the plant doesnt need help. Just light and occasional watering (frequency depends on temp and humidity).

Always start nutes at 1/4 strength to be safe. Once a leaf is burnt, that part will not heal and you lose the little sunfactories.

b&q's own soil is not the problem here i use it and have done from day 1 and never had this issue with it

it is for seedlings cuttings and mature plants it has very very little nutes in it ive just read my bag and it says its not pre fertilized

but he didnt buy the soil. he bought the compost.

And if it isn't the compost then maybe the lights? What kind of lights are you using and how close were they to your seedling?

Then bring on the pics, because I am stumped lol.

Nitro1990 · Feb 10, 2013

unless he has bought a bad batch of compost something is not right i agree

Compost isn't meant for growing in? Its meant as a soil additive to break up heavy soil... Growing in it would be almost impossible I would think? But if Nitro has used it with success I am pretty much stumped as well...

yes that the one i use

Maybe dampening off? Doesn't that cause brown stem and leaf tips?

Nitro1990 · Feb 10, 2013

What is damping off?

Damping off is caused by several soil-borne fungi including Pythium, Phytophthora,Rhizoctonia and Fusarium, which infect seedlings and cause them to ‘damp off’ or collapse and decay.
Damping off can affect most seedlings, particularly under levels of high humidity, poor air circulation and if seed is sown to thick. It is mainly a problem when sowing early indoors or under glass, but can affect seedlings sown outdoors in situ.
Damping off is especially damaging in spring when light levels and temperatures are low and seedlings grow slowly, but may occur at any time of year.

Symptoms

You may see the following symptoms:

Seedlings may fail to emerge (pre-emergence damping off)
Seedlings collapse, often submerged in a mass of whitish fungal growth
