Over watering perhaps?

I will post pics of 2 seedlings I'm currently growing.

Both are in Nft and are @16 days since popping up out the cube.
Feeding them adv nutes sensi grow, @ 450ppm in both tanks.

1st feed was 3 days after they sprouted at 300ppm's which they seemed to like then a few days to a week later they started drooping , in that week I raised ppm to 450 where it's sat since then.

I'm thinking over watering due to the curling leaves and drooping.
The smaller one isn't as bad but today I see the same sorta droop an slight curl in her leaves.

I'm running pump 24/7 but only at a trickle , temps are fine (mid 20's) ppm is stable , infact it's not even moved really in days. I notice slow growth too so I will post pics of both and see what your thoughts are.

And I also see red leaf stems on the smallest one. Not sure what that is tbh. Stress perhaps

You're overwatering and those genetics are strange lol.

The seedlings are green gelato and wedding gelato from royal queen seeds.

I believe it is over watering myself so the only thing i can do is put pump on a timer and change from 24/7 to maybe an hour on per day.

The first fans on the 4th pic, with 3 tips on a solid leaf. Just odd.

i usually hand water until the bottom of cubes (hugo ones) are covered in roots,then put in nft on slow,plants look a tad small to be force fed but thats just what i think and do.

I used to do only clones in Nft so seedlings are kinda new to me in this setup. Even with just rooted clones I cud keep the pump on 24/7 without this problem. Either way im gonna have to try a few things. 1 being turning pump off for a few hours per day (possibly more)

U say force fed , there not even getting quarter strength nutes at this point. Which is below the amount everyone claims to start seedlings on. Even adv nutes recommend starting at quarter strength for seedlings. I know u gotta start off slow and add little by little and I also know that in hydro you gotta feed within a couple days of seed emerging from rockwool as there is nothing there to feed off. So starting at a low ppm is correct in any hydro system.

The red stems have me worried a little , the ppm's are not moving either, I'm thinking underfed on that one as well as over watering but until I sort the overwatering she won't really take much food , I think lol. They both ain't growing much at all right now. What's you're thoughts on the red stems ?

I don't see anything underfed. They all have a healthy green. Just a watering issue. Mist them a little bit and see if they perk up. If not, you'll know.

The feeding is likely the watering issue, so don't sweat it. When the leaves aren't perked up, they aren't flowing much water or nutes.

Red stems I wouldn't worry about. That could be genetics since their fed well. I have quite a few strains that have red stems. Some all are red, some just the fan leaves. Even the main stalk gets red streaks. Red can be interchanged with purple here because depends on what light you're looking in lol.

Didn't mist them bro as I don't have a spray bottle to hand right now. First, What I did was check the roots - there are only a couple poking out the cube and with the pump on a trickle it still is flooding the roots so I decided to
turn pump off for a few hrs a day.

I did expect more roots tbh at this stage but I suppose I'm comparing it to dwc which wud have a bucket full at this age.

I'm gonna get myself another timer so I can walk away without fear of them drying up but that can't be till next week so I just gotta do it manually for now.

I reckon the roots I saw will be in the bottom res within a few days if I can keep it dry enough not to swamp them. Once the roots end up in the res I can relax a little if I've not got a timer by then.

Thanks for replying and thanks for the help bro. Its appreciated

Glad you got it sorted.

Have you thought about a peroxide boost, very mild dilution?
 
I have never needed to add peroxide in any of my grows m8. I would only use or feel the need to use it if I had root problems or to sterilise airlines and airstones after prolonged use.

I get the fact peroxide is good for plants but I use mycorrhizae so peroxide would just wipe them out man.

I got you. Didn't know you were using microbes, bang on.
 
Hello again guys n gals , I'm back with another question but only because I can't specifically see what I'm looking at anywhere online.

At first my green gelato was over watered and has now subsequently been turned into clones due to stem rot.

Now the wedding gelato is showing yellow tips only on the top set of leaves. And there also curling down slightly.

It may be a deficiency bcoz I hadn't changed the tank in over 10 days , before the tank change the ppm's were dropping by 0.02 -0.05 per day which isn't much but shows me she's feeding atleast.

Not once has the ppm's ever risen in this tank so I can't see it being overfed.
Temps are never above 25c with lights on and never below 18c when off. Humidity is between 45 and 50%.

I'm thinking she's starting to show cal mag deficiency but I may be wrong , only due to being left in the tank for over a week.

Can anyone tell me if I'm right or wrong please.

Ph today is 6.0 , with Adv Nutes there's no need to ph even if it's as high as 7.3
The working range of sensi is anywhere between 4.8 and 7.4

I can have ph sitting at 7 in hydro with no ill effect.

I'm not sure if it's overfeeding tbh coz ppm's drop, albeit small increments but still drops nonetheless.

Haven't dealt with all that ph perfect stuff, but as long as it works.

If it's not ph, it's nutes. Your top leaves are quite dark.

Has your res dropped slightly more than normal? That would mean more transpiration from high temps or low humidity, concentrating the amount of nutes in there, making them stronger.
