Any suggestions as to why my runoff is coming out so high after a week of PH’d water flush? Was almost 2000ppm when my feeds were 1200ppm at most.
is there a difference between flushing / and trying to get a nice fade ?
hi man.Depends on the tap water. You could have a lot of calcium carbonate. ...
... Flushing doesn`t work at least you want to save nutes..
Mind sharing your coco specific reasons? First hand experiences?There are more reasons not to flush. Especially with coco.
Thank you for the very thorough response!Coco is constantly supplying K and Na, which it releases as it's a bio product, breaking down slowly. The stuff sourced from south america has less Na, as it's not all grown and processed by the sea.
We need high levels of Ca and Mg in coco foods, to clear this K and Na away. We are talking about the cec here, where the coco has a holding capacity, which would all become K and Na if left to chance. Interestingly, our plant will take Na when looking for K, and can actually use Na in place of K, up to about 70% of the total demand for K. Then it's dead. Before which, it gives a soft tissue growth, which doesn't gel well for mold resistance, or the stomata's abilities to let let the plant breathe.
While some coco suppliers look upon this decomposition to suggest you don't use it more than a few times, you really can if it's kept in good condition. It's best to just keep your coco a good living environment, as you would in soil/organic grows. If you do need to flush, following some total disaster, then Cal-Mag should be used, to get to half the EC of a full feed.
When people talk feedy weed, it's something like the 'snap crackle n pop' of K, which is quickly absorbed by plants. Or the chemical taste of P. Trying to flush coco, will just leave lots of K to eat. With little in the way of competition, or support elements to process it. You can't flush it out, as you just make the cec more K loaded, by lowering other things. The rate K is released from coco, is enough to make you wonder why they put any in the feed. It must be displaced, with Ca & Mg particular favourites for the job. Though if you want your plant to keep processing, not just accumulating, then you don't stop feeding anyway.
Most of the flushing we see, leading to colours such as Mn deficiency, are little more than starvation diets. Mistaken for the end of life effects seen in very mature plants. Plants which more and more people, are starting to recognise as undesirable. Based on the type of smoke they like, not being couchy.
