No Progress In Hydroponic Medium

[bobhead]

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 seedling starting mix with them.

Any suggestions.

make sure your useing the correct cfl's and they are close enough. Sounds kinda like not enough light. :rasta:

Lights are an inch above them.
Like I said, the soil plants are growing just fine.

The soil is .05-.01-.05
Perhaps it's because the hydroponic medium has no nutrients.

But everyone keeps saying seedlings don't need nutrients for the first 2 weeks, some even say for a month.

until they get to their third set or so, MJ from seed only need ph-adjusted water and some distance from light til they get bigger.

ur prolly stunting them with too much light too soon.. get 1 CFl 3-5" above and wait for new growth. :thumbsup:

how are you watering your cubes? are they in the tron already? they need to root well before that.

Get us some pics! U'll get way more replies :thumbsup:

[bobhead]

The soil plants are in the exact same lighting position. So I don't think it's a lighting problem. BTW, they are all the same strain.

It could be watering. I wait until the surface dries out and then water it.
They are in one of those trays with a humidity dome. I took the dome off once they sprouted though.

And I'm using distilled water from the store.

[SmokeMyPiece]

ahhh there may be the culprit.. distilled water. are you adding anything to it? there is a sticky up top about using it.

also, nutes (miracle grow especially) can hurt seedlings.

[bobhead]

So I need calmag plus.

[tinytoon]

Aye and a couple pics wont hurt either. Descrptions can be given all day long but seeing is the best way. I have not had the chance to use STG but I have used RW and I hope you soaked them in PH'd water before use.

[bobhead]

Well, I just did a lot of googling and it seems that all the information is pointing to nutrient deficiency.
Yellow lower leaves, red stems, deformed, stunted growth.

I used ph test strips and tried matching the colors.

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?
