No Progress In Hydroponic Medium

Gooogle :thumbsup: well that SOUNDS right to me. prolly the most common problem around here. Would have been noticed if there were a pic... ok, ok not bringin that up again :jointsmile:

So what PH level did the strip match to?

SmokeMyPiece Reviewed by SmokeMyPiece on 09-01-2010. No Progress In Hydroponic Medium Hi, new grower here. I've planted 5 seeds. 2 In soil and 2 in STG cube and 1 in rock wool. They all sprouted and I put all of them under CFL. The ones in STG and rockwool cube got to the point where I could see 2 small serrated leaves, but they have not made any improvements for over 3 days! BTW, the ones in the STG cube are all twisted bent and deformed looking. I'm concerned because the 2 soil plants are making progress everyday and are looking very healthy. I used miracle grow Rating: 5

Well I tried to match it between 5 - 6 but those color strips suck!
So it probably is off. But after some more research, I realized the hydroponic medium requires a more acidic PH, and the PH affects the uptake of nutrients.
I think this explains why my soil plants are doing much better, because soil can be between 6-7.

But it's still confusing, because if seedling don't need nutrients to begin with, why would having a proper PH be so critical at this stage?

I just ordered a digital PH meter on ebay and a TDS meter.

Pictures, sorry my phone sucks.
As you can see the one in soil is looking good.

I forgot the one in rockwool, but that one is green, but it's elongated and drooping super thin stem, almost about to fall over.

I see. Should I throw these seedling out? It seems like they're dead.
