With cycoflower, I use 1 to 2 ML per gallon.
Thanks for the reply LEDRF and for putting so much time into passing on your vast amount of knowledge.... and for sharing that bud porn!, I got 8oz off a RQS NL under 400w using your methods but without a CO2 tank or air con, they are still on my shopping list!!. If I could ask one more question(I apologise if this is the wrong thread for these questions,) When you used GH Flora Nova under 600w hps how much did you cut back on ec/ppm. I start at 300ppm for the first week, then move up to 450-500ppm until pre flowering when I move up to a max of 650-700ppm(although up until a couple of days ago, 200ppm of those readings was calmag!!)....is this about right when I cut back on calmag to between 60-70ppm?
