The clips work well except don't leave them on too long. Otherwise they won't be able to be removed until after the grow. The stems will fatten up quickly so keep an eye on them.
Day 21 since sprouting:
Left one
Right one
As you can see the right one is still lacking behind. I hope this will improve over time.
Life at the reservoir was steady and ph is now going back 0.1 to 5.8 again. It has been over 14 days that I swapped the reservoir and PPM readings are 290 now (previously 300) waterline is still declining.
Should I do a res change with a little bit more fresh nutes, just top it off with ph'ed RO water or topping off with a nutrient solution?
The lights are at 350 PPFD, should I slowly increase this?

Should I increase it to 0,5 EC? Ppm had dropped to 270 (started at 310 with this res).

i've been following along here One Bell, i'm sorry i don't have much advice as i am just leaning hydro myself. our setups are similar though. and if and when i get to the point you are, where you need to either top off or change out and have to decide what to do, i plan to just follow Aqua's top off method.. it seems simple enough and his method goes by actual plant usage and not a chart and guess.

Ok I'm going to explain a more complex way of maintaining our systems for those looking to use best practices (IMO only) There are many ways this can be done but I feel this gives the most stability for PH, PPM, NUTRIENT RATIOS (super important) especially in systems with a low water volume. So...

i really just wanted to show face and say hello and maybe we can both learn something here.

I've been watching the thread to try to learn what I can. I haven't grown anything in an RDWC system yet but that will be changing soon. I'm in the middle of building one. I think I will run some clones from a future grow for my first run. This thread has been pretty informative so far.i've been following along here One Bell, i'm sorry i don't have much advice as i am just leaning hydro myself. our setups are similar though. and if and when i get to the point you are, where you need to either top off or change out and have to decide what to do, i plan to just follow Aqua's top off method.. it seems simple enough and his method goes by actual plant usage and not a chart and guess.

I would...if the ec is dropping that means it's consuming more nutrient than water and showing slight signs of deficiency.
I just top mine off....unless I have a problem I just top off throughout the grow.

the only thing that can say to that is do it! just dive in man!! i've had every kind of problem and still struggling and can't even explain how much fun it's been. i love the engineering side of it so building it was a lot of fun for me and just the whole newness that comes from it makes it so interesting to me.
i could easily see myself taking a break from soil for little while once i work out my issues.

This is great information....and laid out so even I understood it!i've been following along here One Bell, i'm sorry i don't have much advice as i am just leaning hydro myself. our setups are similar though. and if and when i get to the point you are, where you need to either top off or change out and have to decide what to do, i plan to just follow Aqua's top off method.. it seems simple enough and his method goes by actual plant usage and not a chart and guess.

Yeah, from what I've heard, u wanna keep the ppms and ph stagnant, the sweet spot if u will. Disclaimer: complete newb advice!

it's simple, effective, and takes all the guess work out of it.
you're absolutely correct here.. the plants are already coded on how to grow, it's our jobs as growers just to keep them stress free. and stability is what they like the most.
Day 23 since sprouting:
Right one:
Overview:
So I did a res change this evening. Took about 20 liters out and put 20 liters fresh nutrient mix in there, I upped the EC to 0.6 (ppm 410 x700).
Edit: I lowered the pH so I can test out auqamans recommendation of starting low at 5.6 and let it drift to 6.0 if I got that right.

It also seems that in the right bucket the aeration is minor compared to the leftt one. I took out one bubbling stone which did not create bubbles and replaced it with a brand new one. Not miuch bubble increasement so I need to look into that ASAP. I do have another airpump as a replacement.
I followed this chart for the this feeding:
I mix up buckets of 10 liters for this chart, adding some great white and some ph adjustments.
And from now on I will try out the opping off method of aquaman: https://budbuilders.org/threads/rdwc-advanced-top-up-method-explained-by-aqua-man.209/
And contuining with 24/7 light schedule @ 400PPFD at the moment
I followed this chart for the this feeding:
| ml per liter recomm. TA | half or recommend dose per liter | per 10 liter | |
| micro | 1,2 | 0,6 | 6 |
| grow | 1,8 | 0,9 | 9 |
| bloom | 0,6 | 0,3 | 3 |
| fulvic | 2 | 1 | 10 |
| seaweed | 5 | 2,5 | 25 |
| urtimax | 30 | 10 | 100 |

Use more than one air pump or upgrade to a larger pump. If air pump noise is a concern, hang it from a bungie strap and that strap will absorb a lot of the vibration. Any manifold you're using should have flow control valves on them. Opening or partially shutting those might help even out the air pressure.

If you are looking for a new pump, Alita's are rock solid pumps and possibly the quietest around for their power.

I used the min my fishroom and would never use a different brand again.
Alita AL-6A Linear Air Pump
Runs on 13 watts and has a air output of 10 lpm @ 1.4 psi. Supplied discharge fittings: 3/16" & 3/8" barb, 3/8" barb with 5mm ID

Alita Air Pumps
Alita air pumps are very quiet and dependable. The Alita pumps come in a range of sizes that can drive 6 outlets or over 200 outlets. Alita pumps are excellent for fish rooms and are very easily rebuilt.

I don't use myco's(Great White) in hydro. Not sure if it even does anything?? I thought it needed soil to interact with but may be wrong.

It works, it colonizes the roots, and can still create a symbiotic relationship.
I've been wanting to get liquid mycorrhizae; Orca, to use in my AeroTote

They look darker than your last pic of roots. Are you checking for root rot?
I didn't see if your running sterile or BB....
