superhrive is great and can be used as early as germination, I only use around 2-3 drops per 5 litres of water it will explain doses on the side of the bottle.
As far as nutes there are plenty of them out there which ever ones you decide on, dont use any for the first couple of weeks then introduce them 1/4 dose for a week
1/2 dose for next week and build up to full dose.
Hope this was some help,
get that camera going so i can have a peek!!!

GOOD LUCK:thumbsup:
