Greetings from the Emerald Isle

HI, I have just joined this site and am brand new to growing. On my first attempt I have 12 vegging and 12 I have put to bloom but with limited success as I was over/under watering too much neuts etc so some plants look ok, some not so well.
I have just started my second grow with Blueberry,AK47,Afghani no1, and White Widow, now I'm reading how it should be done I read that some plants need different strength neuts, different ph etc. Can someone let me know if there is anything special I need to do with this second crop.
I think my lighting is OK, I germinate under flourescents then transfer to MH for veg then HPS for bloom.
Any tips will be greatfully received.
Thanks
