One slow vegging plant

[smiteme]

I have a few plants, two from dutch passion. One is strawberry cough and the other blueberry. Both have been living under the same conditions but the blueberry seems to be growing very slowly compared to strawberry cough, the blueberry strain also seems to be more stretched and have a thinner stalk than the strawberry one.

Is this to be expected of the blueberry strain or have I got a dud which I shouldn't bother with?

The first pic is of the blueberry strain and the 2nd is is of strawberry cough

That's some nasty woody looking soil in those chopped soda bottles
Bad soil can cause awfully poor pH conditions, sick plants will be the result.
What IS that medium in the bottles and why does that blueberry one look like its blackened or dug out near the base ? Do I see ashes in there ?

We are going to need alot more information in order to give you further advice on how to proceed

I am running Dutch Passion Blueberry right now. They are super slow vegging plants and take time to get thru the veg stage. I have a thread started with them. Do a search for it,you will see all 4 of them. So far I have 2 females,1 male and 1 undecided. I would spend some extra money and get a good pack of soil,good soil is worth it`s weight in nugz

Get better quality soil with either some perlite, or add some yourself.

then... Transplant..

blueberry is a picky plant, not a good plant for a beginner to learn on
