After two weeks of gradual decrease I am now down to using no calcinit . A few plants are well into the "shutting down new pistil initiation" ... everything I am growing is about an 8 weeker, so odds are that something will be flushing in a couple weeks
I haven't had any issues ... I DID have a tailpiece looking like it was wanting to gag , but I drilled 5/16 holes all over the bottom of every medium container and the roots stopped flowing the only route out ( the tailpiece) and instead started following the wAter out of 40 5/16 inch holes
So no clogging since the root problem is dispersed over the whole bottom rather being concentrated in the teailpiece
I highly recommend this modification , the drainage rate is noticeable improved and I think it helps the oxygenation of the root zone ( as the rapidly draining water level pulls air in behind it )
