Im on my first grow, i found reading the stickys' http://forum.grasscity.com/absolute-beginners/ which provide most of the info you need to get started.

How i manage the nutes:

Fill my res, noting how many litres of water used. Use a syringe to measure right amounts of nutes to add, mix the nutes in a bucket with water, tip the bucket in to res, mix. Check PH and ppm. Make necessary adjustments.

Every 10-15 days dump the res, clean and refill.
