One_bell here, newbie and need advice on RDWC and auto's for 2nd run

I apologize but I have no clue what is going on with those plants. Perhaps @moe.red or @Aqua Man might be around to ask you the right questions to figure out what is wrong. They do look very unhappy at the moment.

Hate to be the one to say it, but I'm wondering if you may have bugs of some sort. Hope I am wrong!

Now, two days later the one on the left seems to struggle:

Currently the one on the right looks better:

I removed the yellow crispy leaves and did some LST:

Last monday I topped the reservoir to 420ppm again, yesterday I switched back to the 18/6 schedule for the lights. VPD is between 1 and 1.2, pH went from 5.8 to 6.1 the last couple of days and the plants seem to be drinking. They do not look really happy

I do see budsites being developped and white hairs are slowly rising, so at least I've got that going lol

How are the roots looking?

No bugs so far, nothing has changed from the previous round except for the feeding (and not using aeroponics to start the seedlings with).

How are the roots looking?

Roots did grow and look healthy, a little bit stained from the feeding both not slimy are something like that.

Goodmorning all,

This morning the one on the left still looks droopy unfortunately. PPM is still 420 but the waterlevel declined so they are drinking.

Drinking but not uptaking the nutrients?

Hmm

What's the res temperature?
Roots look okay?

Scroll back a page and look at his last pic of roots....The one looks worse than the other...and it's has progressed from earlier pics. Also I think there is only mycos in there for BB.

Yeah, I just topped the reservoir again to lower the ppm a bit, it drifted to 430 and has been 420 for the last days since topping off the reservoir with nutrients. The temperature is controlled by a chiller set to 18C and stays between 17-19C. The roots look a bit stained, but that was also the case with the first round I did.

Should I use more beneficial bacteria besides Great White?

Picture I took this afternoon (day 39 from sprouting):

Right:


While in the beginning the left one was way ahead of the right one, things have turned around and now I am slightly starting to worry if the left one will even survive.

Great White may be beneficial to the roots but it's not what is typically referred to as a BB in hydro. The ones usually used work by overwhelming any other that may be in there.....where myco's like Great White aren't meant for that at all. Hopefully @moe.red can chime in maybe and get us straightened out on that?? or anybody that has more knowledge than me.....which again is anybody...lol

it's the best there is and shouldn't "need" anything more.

post a pic of your roots if you can, i'd like to see the staining you mentioned.

enzymes will turn your roots white in front of your eyes!!! ... https://www.amazon.com/dp/B0C8WJX5GQ
