sounds gd for vegging to me! although i wouldnt use a full strength solution, but it can depend on what strain your growing i've found that strains like Nl, Big Bud, WW are very forgiving strains and can handle a nice full strength solution depending on how old the plant is usualy 3 -4 weeks old before id go for full strength..but to make sure id jus go for half strength assuming your plant is as old as quoted. When flowering it is best to use a flowering nute...as normal nutes dnt produce the best buds...the easiest nute to use for flowering is orchid bloom which can be found at almost every garden centre but if money isnt a problem browse the net an see if you can get somea the best nutes around..i.e Canna, Bio-Bizz...gd luck!
