Strange Sympoms with ideal conditions - any ideas?

Ok a but stumped on this one. Clones planted 7 days are growing slow and showing some signs of what looks to be nute burn or lack of nitrogen.

Details:

PPM(ECx700): 280ppm
Nutrients: Current Culture
Water temp: 70 degrees
PH:6.0
Inside air temp: 75 degrees
Humidity: 73%
CO2: 1000ppm during day
VPD: 0.8
Water: RO filtered
Day 7. Went from aeroponics cloner to system 7 days ago.
Lights: running Photontek XT1000 CO2 pro set to 30% at 36". Started first 3 days at 50% at 36" but seemed like too much so lowered the wattage.

All roots look good. No rot.

I did start using an IBC tote as a top off Reservoir and wondering if a contaminant was in it... because everything else looks ideal.

Any suggestions? Why the lime green/dark green multi color and yellow tips?

You need to get your 'lights on' temps up, particularly if you're using CO². Even without CO² you should be shooting for low to mid 80s with lights on when growing under LED. With CO² supplementation you could push those temps even higher. I'm not saying that the particular issues you're seeing at the moment are temp related, but it's a factor to consider and correct.

Calmag was my first thought... thats a crazy no-nonsense hydroponic setup you have, my second thought. I'm surpised you have such little knowledge of plant deficiencies and other issues for having such superior abilities in setting up a top quality grow - my third and final thought..

i agree with nano and hydo.

i'm not for sure on led temps with co2 but probably high 80F to low 90F

and water temps slightly lower

Lol
I've been growing a while
My issue is these new lights are so different then what I had before (GLN720)
New strain

Should just get the ppfd reader for.my hydro X pro

are you running just base nutes or cal/mag as well?

i don't like static EC: it means 1 of 2 things, either that is the perfect EC or you are nute locked and not eating.

i'd stop the CO2 for the time being until you get it sorted out.

Yeah thats what I thought so I stopped it a few days ago

Rez had slime
Think it was the Advanced Nutrients PH down 0-55-0

That or my IBC tote that was delivered to me was not food grade and had residue from something nasty

Complete res change out
Let see

I think your set up will have several counterproductive issues as many have already stated. While using the LED's you want your rooms ambient temps to be between 80-85 degrees Fahrenheit. While running CO2 you could definitely get away with 85-90 degrees Fahrenheit. Unfortunately, it looks like you are in DWC trying to run sterile at water temps of 70 degrees. Desired water temp should be 68 degrees not that you are much off now. And now you got slimed smh. The best way to get through slime is running beneficials. Don't know the ins and outs of your hydroponic setup but if you have any sprayers or drippers or things like that it can be clogged while running beneficials. To get the low down on running beneficials go to the pinned section of this forum and look up top to Heisenberg's recipe. Should help you tons. If you decide to stay sterile good luck as you will be breaking down and cleaning all of that equipment often. And to add you can definitely get those ppms higher for clones like 500ppm


Christ I just saw you are in RDWC. Did you get slimed in every container? Holy Hell!!!

Any updates on this? Would love to know if you figured anything out- I’m having the exact same issue with the same lights and current culture :wall:

Hey
No it was a bit slimed on just the Bluelabs wires in the main Reservoir.
I am using CurrentCulture UC Roots so it's not completely sterile. Stuff smells like pool water so I assume it has some sort of chlorine and or h202

I'm running lights at 70% at 30" but I think it's too much.
I noticed on the outsides where ppf is lower the plant is doing much better
I've just never seen light burn that looks like a deficiency. The clawing up leads me to believe it's too much.

I would put the water temp at 68 degrees and get the PH to 5.8. That would create the most dissolved oxygen in water while putting your PH at optimal levels for nutrient uptake for hydro. Increase your C02 to 1200-1500ppm lights on. All this will be for nothing if you cant raise your room temps to 85 Fahrenheit because these LED lights wont grow your plant without heat.

Interesting…..I was having issues and I been dumping in a shit ton of clear line ( same as UC roots but 5x stronger) and they’re loving it.. Also tried to monitor ORP, they say keep it 350-420, but seems like no matter how much clear line I dump in- the ORP goes back down quickly. Anyways, upping the ORP/oxygen with more UC roots/ clear line might help… here’s some before and after pics over 5 days that mine recovered. They’re growing super quick now. I’m not a professional but my theory is that something (anaerobic bacteria?) is causing low dissolved oxygen, which can cause calmag deficiency and yellowing between leaf veins. Also, are you using the worthless tiny air stones that came with the system? If so upgrade to the circular air diffusers I think they make a big difference……

I reread and seen the phrase “just a bit of slime” being used … I personally take offense to that after the experiences I’ve had. Might as well be just a bit of anthrax.
