I am growing in homebase multipurpose compost which seems like it is high in nutrients. I water every 5-6 days with rain water and I have a fan blowing into the box. I'm using 2 30w 6400 cfls about 3-4 inches above the plant.
I am guessing this is nute burn.
Could anyone give me any advice about how to fix this or if I should wait it out or straight away change something?

Maybe a little more info would be helpful.
Is that soil you mentioned just straight compost?
If that is straight compost, it is way too nutrient rich.
Also compost is living, decomposing matter. It can also generate it's own heat during decomposition. I make compost in a bin outside, and when I stir it in the morning, you can see steam coming off it.
Sounds like nutrient lock out, but without pictures and watering schedule, nute schedule etc.. it is hard to speculate.
If it is straight compost, I would mix it with some other relatively neutral grow medium like Fox Farms Light Warrior or topsoil. (also perlite or vermiculite)
I make my own soil, and I also use compost,(and several other organic supplements) but never just that alone.

The picture is included rocky. I am adding no nutes. And yes, it is straight compost, homebase brand which people have said is too high in nutes.
Do you think i can save the plant or is it too late.
And should I flush the medium just to try to help with getting rid of any chemicals in the soil?
I really don't want to loose my first plant.

And I doubt it is getting too little water or light. I have seen people grow twice as big of a plant with 1 23w cfl. I am using 2 30w cfls for just a 20 day old plant.
What do you think, should I flush it?

Get some peat moss and make your mix 50/50 peat/compost. You will also want to add 1-2 qts of perlite pe gallon of mix for drainage. Then repot pot into new mix.

Sorry, didn't see the pic in the origanal post.
The color and health of the leaves looks ok. (kinda one weird mutated one though)
Sometimes when the leaves curl inward like that it is heat stress. I doubt your lights are causing this.
Compost can get hot. I would stick a thermometer or your finger(thermometer is better) several inches into the soil and see if it is significantly hotter than the ambient temp in your room.
I know this seems like a strange answer, but the leaves color and appearance, doesn't suggest a nutrient problem or deffiency.

I agree with Supertramp, you should mix some more soil.
I wouldn't use any premixed soils as these often have more compost, or other nutrients in them.
Peat is a good neutral grow medium, just check your run-off PH, as this can bring down your PH level.

Good luck with your grow, the plant looks pretty nice, just fix that curling before it starts to effect the plants growth and health.:peace:

Thanks guys. I have already mixed some miracle grow compost (which some people says actually works fine as long as you dont add extra nutes), which has 40-70% peat. I mixed it with some normal garden soil as this most likely has a small amount of nutes in it. about 3-1 compost to garden soil. Then I added some sand to help with drainage. I then flushed the whole mixture with a lot of water so hopefully some nutes wash out and any hotspots are removed.
Do you think this will be fine or do you think i should just go with the buying some John innes and perlite?

And another thing. If I transplant it, wouldn't the same soil still stay around the roots? So wouldn't it still be effectively growing in the same soil, just with new soil around it?

The roots will grow into the new mix surrounding the old mix so no worries...and flushing will do little to remove nutrients from compost. Its a totally different thing than flushing bottled nutes from a container. Also some dolomite lime, 2 tablespoons per gallon of medium would help a bunch. Dont get caught up reading and chasing runoff pH. All this will do is give you headaches and more issues. Runoff pH indicates ZIP,DICK,ZERO about the mediums actual pH. Its pretty much the same thing pHing your feeding/watering solutions when growing in soil. Waste of time, energy and money.

If you don't want to use nutes, then use the MG potting mix. Take the stuff you just made and throw it away, especially the sand. If you are planning on using nutes, use a good quality indoor potting soil mix, and add maybe a handful or 2 of perlite. Fill a new pot almost all the way with that new soil. Don't play with the roots, they will grow, hopefully, into the new soil. Just place your plant in the pot and finish covering. Water gently and everything should be ok, God willing.

So would you guys recommend getting some John Innes compost or B&Q brand compost and mix with perlite or should I just go with what Jimda said?
Or should I get some Biobizz allmix or lightmix? I'm really stuck here

Compost is a medium amendment, not growing medium. Your over thinking it. Just get a bale of peat moss and amend some of it with your local compost. Add perlite for drainage and lime for additional calcium and magnesium and pH control. Dont complicate something that is far from complicated. Chill and grow Bro.

i second alexanders advice. i like a little azomite in my soil mix too. amazon or ebay. the plant looks like it got off to a bad start. the new growth looks good though. but if you only used compost, rich and dense and hot, youre bound to have probs later. make a new mix and plant without breaking up the rootball. dont forget the lime.

Could I just use some biobizz mixed with perlite?
And how would i add lime, is this something i need?

I am thinking of getting some John Innes No 2 and mix it with perlite
would you guys think this would be fine and not cause over ferting?
I read a lot on this soil and it seems good for my size plant
