My first grow!! I just have a few general questions about this setup. Six-Five gallon buckets using edd and flow technique under 600w hps. The only thing that worries me is the feeding cycle. I have seen videos with the same setup that were being fed/watered 3 times a day. How long do they need to be fed? Do i need to change nutrients and water after so much use? Have the timer start pumping water and nutes for 5,10,15 minutes?? Also, if there is a reference chart as to what/how much/ and when certain nutrients are to be used can someone pllleeaasseee hook me up? A simple shove in the right direction is all I need. Thanks to all! Love and freedom.
