Newbie here seedlings looking a little hurt

[imgoingplaces]

hey everyone, so check this out please I added some photos and i need some opinions

Messed up a little on a couple things , little info first

Seedlings are in hydro cloner/ germination station , popped about 1.5 weeks ago and the root systems are developing quite nicely but I'm a little concerned about the leaf

So here's where I messed up and what I've done to resolve

Was watering with tap water at 300 ppm - now using RO water and down to 30ppm

using a 1000w led for the seedlings and initially had it set to 50% intensity at 30 inches height above canopy, saw some stretching at that point so lowered to 24 inches at 75% but I think that's too strong for them based on the pics so - increased back to 30 inches above at 60%

The water level in the Rez was not high enough and there was a couple different times when I checked on them and the plugs were almost completely dry , I've solved this by increasing the water level and watering manually

Any idea why the leaves look like they're wilting and brittle and yellow? I have a sneaking suspicion is the 300ppm

Thanks

just so you know if you want advice you should post pics of roots and tell people what system its going in (i assume flood and drain?) from my experience the same shit happened to my seeds when i put the light too close to them and the leaves never really recovered, i had to wait til new leaves formed..... and the cotyledons are supposed to yellow and die off since thats basically your plants food till the roots and leaves are developed enough to grab nutes out of the water. id use tap water though not r.o, esp since tap has chlorine that can help keep things a little more sanitized. id wait till you add nutes before deciding on using r.o .... and if they're rooted you should put the RR in whatever pot or medium you're going to put them in and hand water..... also a lot of people wait till 3rd set of leaves to add nutes. they usually add 300ppm when 3rd set comes up, then 400 when 4th set comes up.... just my opinion

Thanks, i plan to use rdwc but currently they are in an bubbler germ station/ cloner , will add photos of the roots, i wasnt clear , the water is already at 300pppm out of the tap, i think i was also over watering


Ive got three possible issues

Overwatering
The 300ppm tap water was too toxic
Thr light was too strong

Not really sure what to do, anyone else? would appreciate the help

 

[Gregor Eisenhorn]

Over 300? Damn that's heavy, that's probably causing the problem. Try to get some RO water or some distilled water. Overwatering? I mean that shouldn't happen in hydroponics (?), but make sure the water level isn't touching the net pot.

 

[Budley Doright]

Need to see the roots. I suspect that's your issue but again need to see a root pic. I have clones root in used Res water so I doubt the 300 would have effected them. Perhaps your water in your cloner is to warm, I don't use a cloner so know shit about them. As soon as I see roots they get covered with hydroton and into the trays. I water sparingly (3 floods a day) until roots are established then increase incrementally. Also I ph my water to 5.6-8 right off the pop. This is what I do but may not work for everyone's setup.

Id probably get an r.o filter

hey budley you use root riots or rapid rooters right? at what point do you let them dry out? i feel like people always have different answers I've notice mine like the flood level hitting the bottom of rapid rooter for a couple weeks after being in the table

 

[Budley Doright]

I never let them dry out. They are always moist and yes water always hits just the bottom of the net pot and root riot cube.

 

[Budley Doright]

I base my floods on not letting the thing get dry, but never let it stay soaked either so the floods are changing all the time until there well established then it's just 15 on 15 off. Seems to work well in my system.

really, throughout the whole grow you make sure to keep em moist? i did that but i got stem rot so i stopped and let it dry out and the plants are good now

Yes moist, not sure it's a good thing to let roots that are just hanging in air to dry out but that's just my theory lol. Also I ran three runs or so using misters and went back to a basic flood system. Never had stem rot in an indoor grow ever. Are you covering your cubes with hydroton?

 

[imgoingplaces]

Thanks a lot boys

Check this out , so I got the water changed to ro, switched to 18/6, increased th light to 32 inches at 75% , the plants bounce back really well and they're growing fast, some have roots 6 inches long down into the water, but the roots look a little dark to me,

Ph has been between 5.8 -6.5
Ppm now down to 40
Water temp is 65

The problem now is I think the light penetrating into the Rez and it's hitting the roots

I have them in this aero cloner that you see here just until I receive a couple more items im missing for them to go into 5 gallon buckets, thoughts on the roots?

 

[Budley Doright]

You have root rot . You need to get those girls into the actual growing buckets, get the roots covered so no light. You need to get lots of DO into the water and keep temps down. If you do nothing they will die and may already . As for bringing the plants back to health I used hydroguard but others use different products ranging from sterile to microbial. The only thing that worked for me was lower temps (chiller) and hydroguard, tried peroxide and bleach, didn't touch it but perhaps not strong enough. Here's what a healthy root zone looks like for a three week old cut.

 

[imgoingplaces]

ok will do thanks. The light penetrating caused this huh?

 

[ThaMagnificent]

Guys,

Any ideas on these? 2 weeks from seed on a flood table. Ppm is a little high 1.2 and ph is 6.1. I flood every 6 hours

Ph will creep up to 6.5 daily

well when i first started and the plants were young i let them dry out and they seemed underwatered so i raised the flood level to let the rooter get wet and they perked right up and started growing right so i kept it like that for a while and noticed a bottom part of the stem starting to get mushy and rotted so i let it totally dry out and they been fine and have recovered since. I've read a lot people refer to the rooter as basically an anchor once the plant is developed

i agree with budley, looks like a clear case of root rot to me

the first 2 look fine just a light green 1.2 sounds high as hell for 2 weeks from seed. a lot of people say you shouldn't feed them anything until the 3rd set of leaves and at that point you'd only feed 300ppm. also you should probably throw some more hydroton in there so you can't see the sides of the rooter

 

[Budley Doright]

Ummm possibly, a few things cause it, temps, lack of DO, and yup light, high nute levels.

 

[Budley Doright]

The highest I go in full flower is 1.2-.3 lol.

Not really sure why you got stem rot but I used to get it quite often years ago when cloning in trays and lids, again another bad pathogen I believe. Possibly to many floods and stayed to wet? To much fan action causing stem damage? All things I have heard could cause it. We started using damp off but don't think you can get it anymore.
