Thank you so much for the great info!! But this was way too short,  please if you can and have the interest, expand on the ph drift and the goal to be sought in hydro nutrient res setup?

Cool moving light

Hey Everest,  love your videos
I have a cannabis plant who's ph is swinging down but its EC is also trending down. It seems to be eating nutrients but maybe just the alkali ones? Is there some resources I can find that explains ph and nutrient uptake more thoroughly? Also what PPM scale do you use and why do you use ppm instead of EC?

Thank you🎉 i was looking for precisely that las part of information. Had those problems with a life re circulation system with big active biofilter. Solution.. add coral stone. 😊

Love the horticultural science in this video! Cilantro helps pull heavy metals from the body!!!:)

Good man

:36 I  thought you were separating weed nuggets in the top left!  LOL

perfect

thank you

Love the content 1❤

anaerobic bacteria grows more so in neutral solutions of 6.5 and up. unless it is an acidophile.

your plants are using more water.. so the ph drops because of nutrient to water ratio.. need to have a 2nd reservoir of plain water to feed the main reservoir,  use a float valve in the main reservoir so when called for water will enter..

👍🏼👍🏼up you're the best thank you

Clean/fast/clearly articulated delivery. I am having ph drops over night of
up to 2 points.  I have been adding ph↑ at first just straight into res, then saw that can lock out nutes, so put ph↑ in qt of water add it that way, still turns res cloudy, I believe I read somewhere thats nute lockout.. Plants are growing ok but as a retired tech guy.. I am a little.. ok, a lot.. compulsive about everything.  If any of this strikes a note, drop me a line, tell me how I'm mucking this up.  THANKS, Montana PS, running sterile res, without cooling on this run.  Over all they look great.. A little leaf tip burn on the biggest one, but these plants will deliver. Oh, and I had thrip attack.  SO, 2 treatments of neem oil a month ago,
no joy, the wet applied D.E. right as flowering started. Ok, I'm done. TNX

Rockstar Mann!, thanks for sharing!.

I have found at least in dwc,,if your ph climbs you didnt feed enough ,,if it goes down you overfed

Potassium silicate is cheap and hellps buffer pH needs to be added to tank first to avoid precipitation. It will make the herbs more nutritious and hardier too.

Hey follow up been struggling with this issue for weeks so anyone who is running rdwc this may help without being technical and scientific(because I’m not) there is somthing called the acid rain effect caused by to much air (I believe it’s the co2 in the air but don’t quote me on that)coming into the water and it makes some sort of chemical reaction that drops your ph I didn’t think I could have this issue because I’m using air pumps sized by the rdwc manufacturer but I recently found out that excessive water movement via pump can also contribute I have a rdwc pump and a chiller pump so I put them both on a cycle timer 1min on and 30secs off and now my ph is pretty stable and rising slowly early yet but I am looking forward to seeing if it makes a difference in growth rate

dont u think that u need isolate the nutrient tank from light?

I don't trust people that dislike cilantro.  They're probably the same people that buy salsa in a jar, from a store..
