Last weeks of flower using sense ph perfect bloom for coco

So I've decided to go coco on my next run, 8 10 litre pots under 1 X 400 hps and 2 150 watt dual spectrum cfls. Decided to go with skunk 1# and using advanced nutrients sensi ph perfect coco grow+ bloom. Now, the bloom bottle says to use weeks 1 through to 6. What do I use the remaining weeks? Can't be just plain water. A flush that long would surely do more bad then good. Am I right? If I am, what do I use?

maybe they left that for you to decide? Some people lower ferts gradually, others cut the N completely others flush with sugars H2O2 RO water and what else. i am not an advocate of flushing, i have seen what it can do to grown bud

Right, So I could keep feeding with sensi bloom. I think i' m sold on overdrive though. it's by advanced nutrients aswel. I feel I may have fallen victim to a marketing ploy though haha

Have you used Overdrive yet? I have been sold on it for a few months, my Green Crack was stalled at week six and I had no new bud growth, I added Overdrive and the next day saw more buds on it! I figure I get about a 20% increase with it. Some people misread the directions and think it slows down the finishing of the buds, as long as you follow the directions and use it the last 2 weeks it is not a problem, I have added three days more to the end of my flower but it is more so due to my pheno.

This is a pic of what I am talking about, the strain is green crack, yesterday I hit them with a full dose of Overdrive and today there are six new bud areas. I am 100% sure the one on top and the big one in the middle were not there yesterday.
