thanks Z

I will rephrase a little for clarification. the 1st week of 12/12...you use you veg nutes...that way you shock the plant less...you are changing to 12/12, but the plant doesn't know that immediately...So you stay with the veg nutes for the 1st week of flower...then If you have budblood use it 2nd week flower-only...if not, you said big bud. use that for 4-5 weeks, but as Zandor said. Go find the Advanced Nutrients nutrient calculator. It converts metric to standard and visa~versa...that is what I learned on, It gives you a great feel for the way nutrients values are supposed to modulate up and down throughout the grow. After a few grows; I just started tweaking recipe to suit me, so did Z...and so did all the other Good ole boys. Then I switched to General Hydroponics, for Various reasons (I'm becoming known for my Hydrofarm exploits regionally; So I don't need people identifying me with "POT"! Let's face it...People are not using Advanced Nutrients VooDoo Juice to grow tomatoes...LOL later!
Good luck
