im using a flood n drain system having some problems geeting to grips with adding nutrients do i add fresh water and nutrients each week or should i just top up and just empty and add fresh water once about week 5
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.
