In coco, if you're feeding to 10% or 20% runoff every watering, every feeding is a flush. If you get it wrong one time, the next feeding will set it right. I estimate runoff by the beer can. So for a 1/2 gallon feeding (64 ounces), a 12 oz beer can is about 20% runoff. I don't measure it, just guesstimate looking in the runoff bucket.I'm feeding them again today with a flush....
Mate, the CaCO3 in water is anything but "available"... it's weakly soluble at best, most is locked into molecular form, still bound together...I'm running tap..my tap has a good amount of everthing....
last I saw, a coco flush is best made with low ppm water, up to 150ppm Ca-Mg, plus another 150ppm in nutes, pH to 6.0... This will help purge excess crap but not strip out everything, and fuck up the coco's CEC balance with Ca/MgOk I'll flush and use distilled water....then I'll feed 600ppm of 1part and seakelp....make it around
I plan on cutting it low...I have 7gal of fresh water to the 5gal of calmag and megacrop 1part....I also add hydroguard , yucca powder ,and vit clast I saw, a coco flush is best made with low ppm water, up to 150ppm Ca-Mg, plus another 150ppm in nutes, pH to 6.0...

try to catch some of the early run-off in a clean vessel, then test it for ppm and pH... this will tell you a lot about WTH is going on in there, and helps the process of elimination toward a proper fix!I plan on cutting it low...I have 7gal of fresh water to the 5gal of calmag and megacrop 1part....I also add hydroguard , yucca powder ,and vit c

... free ionic Ca++ is what the plant needs, and the bitch (besides coco's bitchiness with Ca) is that Ca++ is wildly reactive with that double positive charge! Unless there's something to chelate it, it's likely to go right back into carbonated form or worse...
Amino acids and humic-fulvic are you friends here, h-f especially... Excellent stuff regardless of your medium/method, BTW...
...nute makers will chelate their stuff with other synthetic types, but that only goes so far...
An in-pot pH reading will elucidate further... acidity helps with Ca availability, up to a point... Coco likes to be upper 5's-low 6's pH...past this it starts to get iffy in general...

letting things chill and drain/dry out well for a day or so is helpful before resuming reg. feeding... likely symptoms will worsen a bit before they halt,...
