how long are you supposed to wait until you give your seedlings nutes in a bubbleponic set up. I’ve forgotten... and already have seedlings in my set up.
When do you add nutes in hydroponics

Ah thanks a lot. N yeah idk what happened lol.
Don’t think I did it right.
Did the paper towel method and once they popped I put them seed up into the Rockwool.

Man, that rockwool is SOAKED. Let that medium dry out so the roots actually TRY to grow. Lok

They need food right away so your tank should be around 250ppm nutes. If using tap water subtract the water ppm from the total so you have around 250ppm of actual nutes.
I sprouted a bunch of seeds in a 12 pot Rubbermaid tub but just added some screened ProMix HP as a sprouting media to the seeds started. Worked good. I never used rockwool so not sure how that's going to work for you but a lot of guys grow huge plants in soaking wet rockwool blocks so it should work. Use a syringe or turkey baster to suck up some of the nutes to top feed until roots are out of the pots.
Good luck!

There's enough stored energy in the seedling to get it to at least its second set of leaves. You might just wanna wait till you see a root before giving it nutes, considering how young it is.

That two week thing is fine for seedlings sprouted in real soil that has nutes in it but for hydro only it needs nutes right away. How does nature withhold all nutrients for two weeks when a seed sprouts out in the wild?
Starving a baby for two weeks after birth is ill-advised as well.

Wow good stuff you guys. Ive been super stressed out about when I should add nutes.

Thinking I’m just going to drop just a tad bit in. I don’t have a Ppm meter

If you're going to grow hydro you need a ppm pen for sure. Those are cheap enough but get some 1000ppm calibration sol'n with it when you get one.
What have you got for nutes now? With my 3-part AN nutes 1ml/L of all three gives me just over 300ppm and that's what I always start my babies off at in DWC. Without a ppm pen tho you're just shooting in the dark unless you have similar nutes.
With the AN nutes and RO water I never have to worry about the pH so the pen sits on a shelf soaking in storage sol'n. At least 8 years old now and still works fine. A lot fussier to keep it working than a ppm pen tho. With a ppm pen I just spray some ro water on the probes after use to rinse them off then leave it with the cap off to dry. Do not do that with a pH pen tho.

This. That looks soaking wet and asking for damping off.
Also, 250 seems high to me. My clones and seedlings get 180-200ppm total of tap calmag and silica. They're happy for like 3 weeks. I dont add any nutrient until they start showing signs they need it.

The plant doesn't know if it's in soil or water, the storage of sugars is to give time for the plant to develope a root system that's able to support the plant. If you do try to feed it, even a 300 PPM solution you take a chance at nute burn. I would use a mild bloom solution like an 0-5-3 to start and only get it to 100 ppm. Once you see lateral root growth the chances of murdering the plant drastically decrease. Quite frankly I stand by my original post, dont feed it till it tells you it needs fed.That two week thing is fine for seedlings sprouted in real soil that has nutes in it but for hydro only it needs nutes right away.

I have a grow journal on here. It’s called Logics bubbleponic project.
I think a lot of your questions are on there.
I just started a grown a couple days ago so it’s not too hard to catch up.
I’m still only using ph downed water in my grown and not too sure when I should or how much I should atm without the ppm pen.

mall I have is fox farm grow big and cal-mag.
What are your signs of it telling you it needs nutes?

I've only done about 50 DWC grows since 2001 so I probably don't know what I'm talking about.
