base nutes plus ph adjust in neutral or relatively clean water for the win. ec dictated by runoff or slurry after starting with 1.0 -1.2 as a baseline. maybe slightly higher if feeding less than twice a day.
at 500 scale 500 ppm is equal to 1.o ec
at 700 scale 500 ppms is about 0.7 ec
700 ppms at 700 scale is 1.0 ec.
Thanks a lot my friend!
What scale do i use? 500 or 700?
it should say on the meter somewhere.
QUESTION TO ANYONE WHO HAVE EXPERIENCE WITH COCO!!!
Is it really necessary to water flush every single time after feeding? And is it really necessary to then wait for the flush to dry up just as much as you would after feeding?
I mean, as far as I have understood water flushing coco is that it's something that you need to do in order to remove any possible salt build-up, couldn't I theoretically feed them, wait 3 or even 4 days so the coco dries up a bit, then water flush and give them a new feed straight away after the flush? Why this waiting game for the water flush to dry up? Is there a legitimate reason to why I need to wait or is this some remnant from growing in soil, some fear of over-watering that has sneaked its way into coco growing? Because as far as I have understood coco growing is that it's a hydro technique and when growing in hydro the plants can take a lot more nutrients than what they would need when grown in soil, right? Or have I misunderstood this?
I'd like for someone to clear this thing up for me if possible.
BTW
I know that the coco shouldn't dry up completely but everywhere I've looked in forums all around - everyone says that it needs to dry up a bit before feeding/flushing again.
First of coco should never get dry (it only cause problems)
-if you grow in straight up coco you can count on flushing every 2 watering if you want to water only each 3-4 days. but if you get a good amount of perelite in it or some lava rock's or what ever rocks you have around. you will get better draining so you cant overwater as easy as if you grow in straight coco. and ofc you flush your medium just dont over do it or over think it or you can just give less water and feed multi~ times a day its better then you wont get the saltbuild up as much if even at all, if you ask me. (ofc only if you get the time in hand)
It's worth noting that if you're going to flush your coco (which you shouldn't until the very end, water till run off and try and maintain a consistent moisture throughout the medium and you shouldn't ever have a salt problem) then you should do so with a very very low E.C feed, something between 0.5 - 0.8. If you flush your coco too much you risk flushing the 'buffer' away, the coco will then compensate for this by 'stealing' the nutrients from your nutrient solution away from your plants until the buffer is full and then allows the nutrients to become available again.
So always flush with low E.C feed apart from at the end of your cycle to avoid this issue.
As far as I have understood it (and please correct me if I'm wrong) when you let the coco dry up the salts are harder to flush out
