Okay so for promix hp (no coco in it) and/or mothers earth coco potted....could technically use coco/hydros or aqua flakes? I keep hearing aqua flakes as best to use for promix hp (peat base no coco) even in drain to waste and the coco for coco which we have used with good results. But when they got all these dang bases throws you in a pickle when your OCD and want to know exact differences and if one over the other may make a difference. Are any of them cleaner then one another in form of texture when mixing?
I just purchased some Cocos A+B instead of Aqua Flake and the reason was I'm a coco grower. Aqua Flake will work in Coco but not as good as Cocos. I can mix Cocos A+B in a 5 gal bucket and let it sit overnight and it stays in suspension and doesn't leave any residue on the clean white bucket. There are really specific nutrients you actually should use for Coco due to the Cation Exchange it has. It likes to suck up Iron, Magnesium & Calcium or any positive ions for that matter, the special magnesiums etc in the "COCO" formulations prevents this lockout from happening.
If your using Coco always use Coco specific nutrients for the best bang for your buck and insurance. Would Aqua Flakes work? Yeah probably so, but at what sacrifice, probably a big one or you'd end up having to supplement with CalMag additives to fix something that shouldn't have been broken.
ALWAYS use House & Garden Drip Clean with EVERY SINGLE WATERING and you shouldn't have any problems with gunk/buildup if used as directed. I also recommend adding any PH balancers to your nutrient solution in diluted form, put PH UP/down in seperate container of water, stir, then pour into final solution. I noticed some possible lockout when using Cyco PH UP with the H&G Cocos base in RO.
Cyco PH UP is Potassium Hydroxide which is also
extremely caustic and will literally turn your skin colors if you accidentally get ANY on you. Use with extreme caution lol.. After all it does say "POISON" on the bottle. 2 ml brings my 10 gallon reservoir from 4.5 to 6.2 PH.. Quart (946 ml) is 10 dollars where I shop.
