GDP and God's Gift hydro grow log

[TheHourLateGang]

How long should i keep the ppm at 700?

When I raise the concentration of nutrients what ppm should i set it at?

Is my PH at the right level for Granddaddy Purp and God's Gift?

I am using General Hydroponic's nutrients right now, its called Flora Nova Grow. Has anyone else used these nutrients and were you satisfied with your results?

Am I missing anything that I should know about?

Any thoughts or comments on my previous question about the nutrients?
