The correct soil for repotting

Hello darlings.

I'm about 2 weeks into a CFL closet grow with 2 lowryder 2s coming along nicely. I've got them in homebase own brand John Innes No1 atm. My question is this.

When I come to repot am I OK to use the JI No1 again? I know it's for seedlings but will it adversely affect my grow? I have nutes to add, so lack of nutes won't be a problem.

I also have some homebase own multi-purpose compost. Should I use this to repot? Or should I just put my hands in my pockets and buy John Innes No2 and leave the nutes out for a couple more weeks?

Open to all ideas.

Thanks.

hey u frm england? U gt piks?

The only difference in the two is that JI-1 has half as much nutrients as JI-2, right? Personally...I prefer having more flexibility and less nutrients in the soil getting in my way. Especially if they aren't the nutrients I'd add anyway.

Do you have decent nutrients or are you going to be feeding the ladies via transplanting? If you have no nutrients, this might be a problem once deep into flower.
