New Grower Seedling problem! Help!

[manny]

Hi!

I just started my first DWC grow ever and i need some help so I would really be thankfull if u guys did.

So.. I planted my seeds in root it cubes and they grew up tall very fast so on day 3 I transplanted them into 4 inch rockwoolcubes that had been soaked in a nutrient mix with a EC of 0.8 and pH adjuted water of 5 pH for about a week.

Now a few days later the two biggest 2 ones have bent over right at the top and I dont know why.

I have the humidor on 24/7 at 75-90 % and a holographic series 1 as a light

could it be simply because they´re to heavy on the top for thier own good?

I havenet watered the rockwool cubes because i dont know if I am supposed to so could it be that they dont have enough water?

I will appreciate all the answers and all the info I can get !

hey manny could you maybe post a pic? it sounds like they stretched too far, are they about 4 inches tall or more?
try and stake them up until the stem thickens up some.
if the rockwool cubes start to dry out give them some more water

 

[manny]

Yes they are aatleast 4 inches tall. thank you I will do that immediatly!
But do I need to my lower my light to? just to stop from making them any taller
thank you so much

 

[woody]

how high do you have it, i'll have to double check but I think a hs1 should be about 50cm away for seedlings

 

[manny]

I dont really know at the moment, I will meassure it tommorrow.
Only one more question, if I water the rockwool should I water it with the same water/nute mix that I used to soak them with or just pHd water?

I would keep using the light nute mix, but just wondering why you set the ph to 5 sounds a little low, most aim for 5.7-6.2 in hydro

 

[manny]

from what i´ve been reading the rockwoolcubes does have a tendency to pull the hp up so if I set the ph to 5 it gonna rise toward those numbers (i hope at least haha)

Manny, I have been using rockwool cubes for germ and initial few days of growth. I keep them in a shallow tray with shallow water at all times. As soon as any little root appears I transplant the cube straight into the final resting spot. And while I don't have HS1's, I am growing under LED's as well but always keep them under CFL for the first week, allowing the new seedlings to adjust to light before bathing them in LED brilliance. I typically get several inches of stretch in the first 8/9 days as the plants put on new leaf pairs. I keep the CFL's about a foot over the seedlings and then 18" to 24" under the LED's. Since you are growing in DWC, watering should not be an issue. Hope this helps.
