I am so confused.

See? This is what i mean. Lol.

This is N toxicity....

Notice the dark green leaves clawing down?

This is N deficiency......


Notice the yellowing lower leaves and light green uppers?

I know how you feel though. It is kinda confusing at first.

Yes, mine were more like the bottom one--deficient I think.

Also, as for the light, it is set on 20% at 30", but I am wondering if i should use fluorescents until they are big enough. I have tried various levels of ppm. I think my very first was around 200. I will go back to that.

Yes, put your seedlings under a T5

I would suggest starting with a mild organic soil like fox farms happy Frog, I. 3.5-4inch pots for your seeds then moving to ocean forest in 2 gallon pots then to 7-10 gallon pots to flower and not feeding them anything. Just water them and up pot when they need it. Then watch how the plant grows and learn from it.
Then after a couple of grows move on to hydro if you still want to.
Don't give up and welcome to RIU!
Good luck friend!

I may do that yet. But I still want to get the rockwool hydro down if I can. I've invested a lot.

Your subsequent grows will be better. My first grow choices were pretty bad. I ended up scrogging bag seed that was vegging for way too long in hydro 5gal buckets. scrogs + dwc=bad idea, flip to flower where the rootball is already filling the bucket = bad idea, and growing bag seed for first grow = bad idea (had one plant hitting the roof of the tent mid stretch, the other was short and bushy), I also underestimated the speed of growth of DWC and got root rot. I was trying to apply my pepper growing experience to cannabis which didn't work out as well as I had hoped. I now grow in soil, much more relaxing. haha I do agree with others on rapid rooters. They work and no precharging with pH this or that. I just spritz them with coconut/aloe water every few days and keep the heat mat warm.

Thank you for the info. I may change my medium soon.

I've had good luck with RapidRooters on a heat mat. Just make sure the channels stay full of water and mat is at ~82 degrees. Open vents on the dome as you see roots. My last tray of 50 had 49 rooters. This was cloning... but works just as easily for seeds.

Ah. I think you just pointed out something important that I skipped: I don't have my cubes in trays at all. They are just on a metal grate under the light. I figured there are only 2 or 3 at a time, not really enough to bother with the tray until I stop killing them. But maybe that's part of the issue. I need those channels under the cubes?

May try them, thanks! Have a mat and the trays and dome already.

You barely want them wet for a baby seedling.
soak them in proper ph water, then rinse them with your ppm and pH’ed water. Then stuck out a lot of squirts. You will be able to see just how much water the cubes are holding and you will say wow ya that’s too much

 

[StonedGardener]

Ahh. Great suggestion on the meter. Will try that. Thanks!

Glad it helped.....if you ever use a dehumidifier( I run at approx 35% RH) clean drop out bucket once a week....a bacteria/mold forms in slime at bottom of bucket......never seen anything grosser ( at 200X power.....looks like something from "Hell"....) Growing kinda like picking out music or deodorant, everybody has their own preferences. I'm old school and keep it as simple as I can.............

I wilk try that. I have a syringe I think will work. Thanks!

Yes... it wicks up the water at a good water/air ratio. When the dome is on, it’ll be raining in there. Heat mat is very important to success as well.

Thanks for that!

I've found rockwool to stay wet for far too long myself and now I cut it down a little and now it takes less time to dry which is perfect for daily waterings.
I first use a 1.5" tube (actually the tube from an outdoor pathway light...lol) and slowly press it over the top of the cube.
(I also filed the edges of the tube to make them sharp, so it cuts much easier and less mess.)

This leaves a tube shaped piece which i then cut in half so I'm left with 2 puck shaped pieces of rockwool.

The pieces that get chopped off in step 1 get used to plug the hole(s) in the center(s).
I use these for 1-5 clones at once in a tray with 6-8 cups.

So you just germinate and grow your seedlings in those little rockwool pucks? Another unique idea for me to put on the list of options. This forum has been a great source of info so far. Good friendly community.

Thanks!

I generally do the paper towel germination then move them into solo cups and soil.
After the plant has grown up some I take clones (this is where I use the pucks above) and grow them to flower in a homemade DWC system...if its a good strain I may grow another pair of plants or just keep the mother for awhile while I'm growing another strain...I've even made seeds of a few I liked...have about +25 strains I think now...lol
I find its easier to get 2 clones that are growing fairly equal vs. 2-4 random seeds to grow equal or even show the same traits.
Now mind you I could germinate in rockwool, but I don't really have a need to when soil is an easy option.
Oh, and you're very welcome.
And welcome to RIU
