Jesus that's one plant!?!??! ^^
For coco (and you'd have to read the better part of 28 pages of threads to get to this) a member on IC mag nailed down a ratio that's working pretty well for me right now.
6ml Micro/9ml Bloom per gallon in RO water turns into about 5.85 for me. For seeds, you start in party cups with damp (just water) coco, then add a tiny little bit of 1/2 strength nutes until you see the very first indication of a LITTLE bit of runoff. Place a tbspn of dry coco on top of the wet medium, drop the bean in the loose dry coco, then drop another tbspn of coco on the bean to cover. Place a plastic bag (like you get your veggies in at the market) over the top of the cup and seal it shut with a tight fitting rubberband. The moisture from the wet coco will evaporate up into the dry coco and gradually moisten it without absolutely drenching your seed in nutes right off the bat. I leave the bag on for 36 hours then remove whether I see a sprout or not. Once you see a set of true leaves I then feed with the same 6/9 ratio every other day, watered down to about 300ppm, pH'ed to 5.6-5.9. Starting day 7 (after germ), I feed at about 400-500 ppm every day. When you feed, add nutes until you see just the tiniest amount of runoff, then stop. The goal is to exchange the liquid in the coco daily. Doing so increases the cation exchange capacity of the medium and keeps the plants' root systems growing. If you were to water then let it dry out like promix, you're going to burn the hell out of your plants because as the coco dries the nutes will become significantly more concentrated as they drop out of solution and the pH will go completely out of whack. By watering daily, you actually oxygenate the roots by allowing an exchange of the old "used" water for new "fresh" water. Per Gr3atful H3ad (the creator of this grow style) you don't ever want to use non-nutrified water unless you sense a SERIOUS over-fertlization. If you feel like you need to remove some of the nute concentration, add water, but not so much that you see runoff. This will keep the nutrients that are already in the container in the container instead of rinsing them out, but will not introduce new nutrients. If you were to "rinse" or "flush" to the point of getting tons of runoff, you can actually sort of neuter the coco by removing all the cations and making it more or less useless.
From the man himself:

is pretty much the regimen I've settled into...
I'm running the 6/9 until the production of new calyx begins to slow... a couple of weeks into flower production on faster flowering strains, a bit longer for 70+ day flowerers... Some of the heavier finishers get the extra 3 ml/gal of bloom that last week... then 0/9 up until flush time...
I have been trying minor variations... upping the bloom during veg gave a bit of Mg/Ca lockout... Leaving out the micro too early looses bud mass... Leaving the micro in too long makes flushing more difficult... Not flushing long enough affects the quality of the flavor and burn... Watering with no runoff at all causes lockout and flushing issues late in flower... Watering with more than a tiny bit of runoff is a waste of nute, and environmentally irresponsible...
No matter what variations I've tried, I seem to end up right back just about where I am now..."
So far I'm up to day 10 on my Mossy strains (PAK/JEM/M. Drag), just transplanted into 2 gallon smart pots. I'll let you know how it goes, currently diluting my feeds to about 500ppm (full strength is just under 900). So far the plants look great, and unlike every other grow, it's impossible to over-water. When using coco, you have to ignore the fact that it looks and feels like soil. It is 100% hydro and if you don't water daily, you'll starve your plants and cause lockout.
