Grow Mediums Cal mag for final flush?

[Philip]

I am about to start my final flush on a couple of sweet tooths (or would that be teeth), a tangelo rapido and grape muerto. They have been under a Mars II 700 in a 3.5x3.5x6 tent. My question is, because they are under an LED, will I have to add cal mag to the flush or just straight ph'd water?

Strait ph water is best.

The idea of the "flush" is to wash out nutrients, particularly their water-soluble salts. You do not want to be adding these, which is exactly what cal-mag supplementation involves.

Good ol' pH'ed water, Brother, 10-14 days is best if you can. Welcome to the home stretch!

Philip-- I think some sort of rinse agent is best when in coco,...? -certainly no other inputs,... as for how long a time, check with Ronin or Truu to be sure, on both accounts... Sledgehammer, Clearex, Floraclean, etc., are flushing agents that help knock loose the bound up cations still stuck to the coco,... again, check with the pro's that knows :smoking:... I'm not a coco-savvy grower, so the specifics I'll defer to the experienced!

Well, I longer seem to have my coco nut badge anymore. But, I have done a few grows in coco. So ill jump in. What I have always done in coco is really lite nutes. Round about 100-200 ppm. P.h d water would be my next fall back. Sledgehammer should work pretty good or final flush, by I think advanced nutrients.

I wouldn't use cal mag at this stage. Just a waste. Imo

Roark - thanks for the input, bud! I'll see about getting your coco-nut badge hooked up again,... I think there's been a thread tucked into the Live Help section about this,...old stuff didn't carry over from the site software change! :smoking:

@Philip
If you are using synthetic nutrients I would recommend as @Waira suggested using a flushing agent(sledgehammer,florakleen)
If your using organic nutes, then plain water will work fine.
In the final days my ladies get water only. No ph'ing.
Congrats on getting your ladies to the final stage

Thanks to all for the informative responses. I am stoked! Ronin, thank also for the rep.

I usually used Florakleen by GH and RO water because it was very cheap especially when buying 10L at a time
