give us a bit of information. So you are growing hydroponically.
ph, ppm, water source, nutrients, enzymes and humidity and temps of grow space as well as your rez.
She looks bad cuz of temp and humidity i think
boost your humidity to 75% at 26c. How far is the light from the plant and what is the light intensity if you have one of those adjustable once. I guess you can see some of the roots?
To be more specific try about 10k lux for a few days
10k lux right now especially with 20/4 cycle.I have just moved the light, 2 foot is as high as I could get it from the top, however I adjusted power slightly and will make better adjustment. As for the Humidity, should I also change that or see how I get on with the light first?
10k lux right now especially with 20/4 cycle.
25c 65-70% is probably ideal but you can get away with lower if you don't kill en with light.
You ppm are way to high depending on source water 200-300 or 300-400ppm should be more fitting.
What is your source water?.... tap, well, RO? Sounds like you have an alkalinity issue if your ph is swinging that much.
What ph down are you using?
Ok that all looks good. May need some magnesium later on because of the high calcium in the tap. About 400ppm should be good right now.Perfect will do that!
I will adjust humidity accordingly! Easy to do anyway, can punch a few numbers in my pc and the magic will make the rest happen.
My water comes from my tap and comes out the tap at 190ppm. We have low chlorine here and no chloramine so I just left evaporation take care of the little that may be in it before mixing. I can mix lower strength nutes ASAP if my mix is too high for this early
Source water is just regular old tap water, it's a hardwater area and the PPM out the tap is 190
Vitalink - PH Down
(81% Phosphoric Acid)

Ph adjust last and think you will be in a good place after small adjustments.
You're feeding them too heavily. Those are small plants with the cotyledons still attached.A lot of these details are in the original post
DWC Hydro. Oxypot with airline going to 2 long bar airstones. Plenty of aiflow. Roots look healthy and white.
10 Litres Tap Water left to sit for 48 hours. Initial PH before anything: 7.8
Initial PPM of water before anything: 190PPM
Nutes: General Hydroponics Trio feeding was:
Micro: 10ml
Gro: 15ml
Bloom: 5ml
PPM After adding nutes: 816~
PH After adding nutes: 7~ (from memory, did not make note)
PH down to 5.8 stable after 10-15 minutes
Enzymes?: None?
Humidity kept between 40% and 50% via a humidifier and humidity meter turning it on if it drops below 40% RH
Temps:
High: 25
Low: 20
Current PH is 6.8 it seems to have shot up after 2 days
Rez temperature is the only thing I haven't monitored...
Maybe I need to drop my Humidity now?
Because ppm changes and knowing the input you can see if they are eating or not and how much. It gives you a lot more info. I dont understand why someone would do hydro without it... thats almost like saying why test ph in hydro.... its so much usable info.I don't understand people and measuring ppm. It has directions on the side of the gh flora bottles. Add 5ml of calmag and follow the instructions on the side of the bottle and you're almost guaranteed to get good results.
I've never grown in hydro so that's a different story. In soil and coco since after my first few grows where I over thought everything and loved them to death I have never tested ppm and also never had a problem that wasn't easily spotted and fixed.Because ppm changes and knowing the input you can see if they are eating or not and how much.

I have honestly never heard that said before... im curious as to why you would not want to test ppm?
Oh definitely i see where you coming from on the soil and organic nutes.I've never grown in hydro so that's a different story. In soil and coco since after my first few grows where I over thought everything and loved them to death I have never tested ppm and also never had a problem that wasn't easily spotted and fixed.
I feed my plants by how aggressive they are growing,how big/old they are and in what stage of growth. I tried messing with ppm back when I grew with fox farm nutes and burned the crap out of my plants. I threw the tds pen in the drawer and have had amazing plants every time since by following the instructions on the bottles. I do have a few other secrets to my success but the main one is following instructions.
