Dry hanging leaves during night

Wouldnt want to be on the road while your driving. Guy has root issues and your telling him he dont need his water cooled down. Some people dont grow in a cool basement, some are using real grow lights and not shitty led, and with cool water you dont need to waste cash on root health crap that is expensive like you say, they want your cash. If your gonna help someone make sure you have the right info. Not tell him he is overfeeding when his plants keeled overnight. Overfeeding would never end like that... oh but you know don't you.. amateur

I have my Class 1 license and I learned that in a classroom but when it came time to driving... Driving was very different then actual theory and practice.. Your logic and reason maybe sound Gmslave but there is a lot more going on to Cannabis. I got my Degree from being CRAZY ha ha. you do you friend that's all we can do right?? Honestly I appreciate when someone peeks my interest. But I don't like to argue so I'm just gonna leave this....

Degree in horticulture and marine biology here....so know one needs my advice, that's fine dont take it...

Like I'm autistic so I wanna just keep going on and on.. to try to explain my point... But I seriously can't stress this enough... lots of people don't use water chillers... Me included lol.

or if they know they have bacteria problems with there water... Water is actual a fairly clean and stable growing medium.. Why do you think it makes for such great growing...

like across multiple tanks in multiple systems with multiple plants... I did them I ran side by side.. Saw zero difference... Hydro growers don't need to spend money on water chillers.. They can if they want too I guess.

@gmslave I appreciate your advice man... But I don't use water chillers at all period... weird right?

Do you or did you gave slime build up in your res or planters? Pythium will do this very quickly, it is not from overfeed. People that run dwc or rdwc really need a chiller, a 24/7 nutrient and ph monitor like the growboss. Cheaper then bluelabs monitors. For root real good root health in dwc or rdwc it is vital to keep your water temp in your rez down at 62°. That's were the chiller comes in. Rdwc and dwc is the most time consuming way to grow. To do it right you need the chiller the monitor and to be safe you need to take the plant from the planter once every 2 weeks at the very longest and scrub out each girls home at keep them clean. That's the first thing you should do now. Then mix some hydrogen peroxide in your water and run that for a day, then empty out your rez and replace with 600 ppm 1.2 ec and make sure wate stays at 62 to 68 degrees max. If you live in ontario I have to chillers for sale. I went back to the easiest way to grow with great results. Straight promix or nutrimix hp . Hardly any work. No problems.... hope this helps. Cheers

I talked to this grower privately about his situation this is why I am comfortable with posting I believe he would be okay with it as well.

And I see this a lot... Nutrient companies don't change the schedules... They just wanna sell nutrients.. So you using way more then you have too.. Makes them money... So why would they change the schedule.. especially when if you look closer.. You can see all sorts on information.. that specifically states this is a guideline only.

Okay just to try to explain a bit further... It's a lockout yes but it's cause by very high nutrient content in the feeding... Plants don't have way to control how much fertilizer or nutrients you give them... WE think they do.. They don't they just do the best we can with what we give them..

It's a lock out. Most possibly because of the state of your roots... The dry, yellow crispy leaves you see are the buds sucking out the potassium. As to what to do there.... I would suggest changing the res again make sure its at a stable temperature and trim back the roots a little. Strange as they've looked quite healthy until now

Looking at your photos it started with a magnesium deficiency now you look to have root rot . Looks like that plant have unwanted pathogens in your root / not enough oxygen in your hydroponic tank Or light leak or heat

Okay I did have a couple answers up.. I'm gonna remove not because of whatever but I don't wanna flood..... um if you would like help from me I can only do it in pm as my brain will need more information to help.
