Very Slow

[Old Toby]

Hi all I hope you can help me out

I've got 4 easy sativa's growing,all are well except that 3 of them aint developing like the 4th. 1 is tall and very bushy (growing in a mixture of potting and garden soil) while the other 3 are lanky and not very bushy (growing in top soil, it was all I could get at the time)
ph's are neutral and I have been using Biobizz nutes.
Any help appreciated.
p.s. hope to get pics up soon.

Sounds like you answered your own queastion.The 3 that aren't doing good need to be repotted in good soil!
