Help please - leaves curling up - with photo

[jahmid]

Hello 420,

Ill give you the details of my grow first. Im growing 4 cream caramel auto plants, in my greenhouse (UK). Its still early days, only one is showing leaves at the moment. Its my first grow, so im still new to this.

The problem is that the first set of leaves on this plant are curling upwards (ever so slightly starting to turn a shade of yellow, I think?). I take it this is a deficiency of some sort, or maybe over watering? im not sure. Either way could someone explain why this is happening and how can I sort it out.

I would rather catch it early than let it turn into a massive problem.

Cheers,

temps might be high , the leaves taco when too warm

When looking online I thought this might be the problem, but temps in the UK have been 24c at most, and I leave my greenhouse wide open throughout the day.

So im not sure if it is down to temp?

The photo was taken 2 days ago, they seem to be worse today

Anyone?

im uk also / N Ireland , the green house will heat up more than out side , have you checked the temps beside the plant , and is your humidity good

 

[NuttyProfessor]

how often do you water also

 

[jahmid]

Not checked the temps inside the greenhouse? You think it could be overheating then?

Im not sure about the humidity either mate. Do I need to have a high humidity?

That is my greenhouse I leave the door open all day to keep it ventilated, it is also slightly raised so air can get through in the evenings.

Have barely watered it the past week (the pot feels dry and warm). But previous to that I had over watered, I had one seedling die because of this.

Cheers nutty!

above 40 is good for veg , then get it down after she flowers , you can buy a little clock on ebay gives your temps and humidity , they are cheap as chips ?

like this

Ok im on it. Thing is I have tomatoes, cucumber, peppers and flowers in there too (need the camouflage!) will keeping it humid ruin them?

And do you think this will sort the plant out? Want it to be healthy!

Also can I feed it any nutrients yet?

Just checked out your journal, well done!

Nice one

no food yet ... dot let her dry too much , next time you water lift the pot , judge the weight , every time she is too dry you will know by the feel of it . i used to use nutes but now i build my soils before i plant , then i only use compost teas

feck mate at the minute ive half a dozen journals going haha , heres a look at my out door ones

 

[jahmid]

They look quality mate! Ill be sure to check out your other journals!

I used a no npk soil to germinate my seedlings in, because they are autos, ill leave them in those pots. Its my 1st time so ive just gone for a pack of outdoor BioBizz nutrients.

Hope they turn out as well as yours!

biobizz will do the trick , just dont go too mad ... half strength most of the way , autos wont take as much nutes as regulars
