Seedlings Dying Off Someone Please Help Got Pics

my seedlings r dying one by one can does anyone know whats goin on

Didn't we go though this a few days ago? Yes we did!! https://www.rollitup.org/marijuana-plant-problems/430876-seedling-2nd-pair-leaves-turning.html

what's in your res? probably transplant shock.

Yea we did just stressful to see my baby's dying in front of my eyes, think there givin up on me

Right now in my res I have tap(added last night) water ppm 150 add nutr till water was at about 250ppm ph has been good at 5.8-6.0 also checked my ppm this morning and it read 300 why is this? I just Pick up a tds meter first time Ever testing water meter reAds 950ppm

did you add ph up or down cause that will increase your ppm. And I don't do hydro but your ppm's seem a little low

That could be it add some ph down then never tested it again as for the ppm should it be high?

You def wanna get a second opinion on this but I'm thinking that they should be around 500-700 ppm and don't forget to subtract your beginning ppm and whatever else you added that would raise your ppm. If I had to guess i would say underfeeding but like i said get a second opinion cause im not a hydro guy.

That sounds high for seedlings. I'd focus on keeping a low amount of nutrients at the right pH.

Like I said Im no hydro guy but I've tested my water for my soil after adding just 2 ts's of ffgb and it was around 900 ppm and they handled it just fine. I prolly shouldn't even be chiming in but im bored and don't have shit to do

the nutrients are too strong for little seedlings.
0.5ec or 500ppm is enough but it looks like there is more going on than just strong nutrients.

i looked at that system your running and it is either an aeroponic or nft gully system and im thinking that the seedlings roots are not growing out of that rockwool plug enough so you are basically drowning the roots with overwatering.

you would do better if you stand the plants in a tray and top water them with weak nutrients every day by hand until the roots grow through enough and you have a few sets of leaves growing out before transplanting to the hydro system. i found a couple of pics to help with root size before transplanting.

So what ppm do u think I should be lookin for

Those are not ROOTS!!!! Those are sprouts and should go on your Sandwich!!!

Dam those are some fat roots.

Thanks for the advice just turned off the waterin system I've been watering with a weak mix as suggested by spark so guess I'll just be using that, also when it comes to the wAter in the res should I use water sold at the food market or is tap water just as good

How many times a day Do u think I should water them by hand
