the hanna has never been calibrated i bought it new. i wait till the little clock goes away before i take the reading and it says its calibrated.
the plant on the left was pretty droopy before this morning. it was also starting to yellow from the middle out. the one on the right has been doing the best and has actually looked fine but didnt grow much at all until this morning. the third one is in the worst condition. roots seem to be growing but they are more stretching like the plant and still very thin. actually it lost part of its roots before i took it out of the net pot but has since grown part of it back. leaves on the third are still droopy and is still a little yellow same as the other but is slowly improving out of the net pots. it was possibly the ph in the rockwool. i wasnt worried about them dying last night so experimented with them by taking them out of the net pots to see if i could change the ph before the died. i couldnt get the ph under 6.0. will that go back up or is the soaking thing like a flush to remove the limestone? i think thats everything. oh im using a window ac to maintain temps and thats been 73-80. varies quite a bit because my lights are on 6pm-12pm. i try to keep the lights off on the hottest parts of the day so at night without adjusting ac temps can go down to 72-74.

To help with root growth, have you tried adding a little beneficial bacteria? What about General hydroponic's Micro? Once the root system develops your upper growth will start stretching.
Also consider that my main experience is in coco on an ebb and flow recirculating system.
I wouldn't worry too much about what's happening up top until they are out of seedling growth and have started veg growth. Concentrate on getting those roots anchored.
Are you going to continue growing the strain after this batch? If so consider selecting 2-3 of the best plants and concentrate all your love into those few good ones. Your problems could also be due to just bad genetics ( the slow rooting plants), which you can't do much about. But once you get clones from the good plants to start the second batch, at least it will be from the plants with good genetics. By then you should have a good idea of what all that particular strain needs to flourish.

Go purchase a bottle of PH 7.01 and PH 4.01 and calibrate your meter. It's best to calibrate it once a week but every other week should suffice. If you need help calibrating PM ( private message) me. I'll be glad to help

What I did was germinate the seed in paper towel, soak the rockwool in the 5.5 water, put the germinated seed in root down. Put under a 42w 6500k CFL until roots were showing out of the bottom of the rockwool. Then I put in the bubble bucket with the water at the bottom of the rockwool. Right away I started out with 1/4 nutrients and 5.8 ph. You could almost see it growing it grew so fast.
I would suggest trying quarter strength nutrients. Also calibrate your PH meter, I went to the hydro store to see about how to calibrate it and he looked at me like I was crazy that I didnt calibrate it right out of the box.

Also check the temp of the water, you ideally want to be under 70 degrees but def not over 80.
Also make sure the res is light tight, if light gets to the water algae can grow.

can anyone else support feeding these at only 1 wk old? the water has 140 ppm. no offense im just trying to get some supporting info so i dont kill them.
the way I saw it was the reason you dont use nutrients at first in soil is because the soil itself already has some nutrients in it whereas distilled water(what i used) does not.
