I know rockwool has no nutes but...

Take a look at this pic. Both of these seeds were pulled off of the same bud from the same bag of smoke, germinated in the same paper towel, and planted at the same time, one in the cube and one in FF ocean. They are currently 10 days old. They have both been fed nothing but growroom temperature water with a ph around 6.8. Look at the difference. I have 6 seedlings going in cubes and 5 going in soil, and its the same story across the board I just used these 2 plants because they are the healthiest looking. The one in the cube looks perfectly healthy to me, just way stunted compared to her soil siblings. The messed up part is if I were to nute the ones in the cubes they would burn. What's the deal? Is it really just the nutes in the soil? Based on this I wouldnt bother starting seeds in cubes. Anyone know why the one in the cube is so very tiny when its almost 2 weeks old?

Yup, there's nutes already in your soil. You can use nutes on the one in the cubes just in light doses until they're older. Like maybe 1/4 strength on the nutes while theyre young

firstly your ph in your rockwool is way out, it should be 5.8.

secondly just because it came out of the same bag doesn't make it the same smoke. No one intentionally seeds weed without holding back all the seeds if its for sale and its got seeds it was a fuck up so chances where the father could be a number of plants, most bagseed that comes out of weed where the seeds are not too densely populated turn out to be hermie because thats how they got there in the first place. If it were pollenated by a true boy then it would have a far denser population of seeds. you could get lucky and not have it turn hermie, but your either going to get females or hermies.

The rockwool does contain no nutrients, but if you have not ph adjusted the cube in the first place and then feeding it the wrong ph constantly how do you expect it to be happy

the rockwool one is way behind, when i get home from work tonight i'll take a pic of one of mine that is in a rockwool cube that is just 14 days old

do you think there is anything I can do to move this along? the reason I'm concerned is that my last batch of plants (R.I.P) I just stuck the seed in the cube and the next day it was a half inch tall. It was a diff strain but still. And I didnt bother ckecking the ph last time but it came from the brita on the tap just like this time and it comes out the faucet ready at 6.8. I will try giving the cubes some 5.8 water. I'm considering using a bitch dose of bloom nutes and a couple drops of superthrive. I read that bloom nutes are better for seedlngs because they like the p and k more at this stage for roots and crap or am I way off?

No need for nutes this early, as easygrinder stated, your PH is more than likely the cuprit.

Probably your pH meter !! Especially if your tap water is 6.8 , out here in California tap runs almost 8.0 !!

the coloring of the leaf suggests that it is not short of nutrient. ph is your biggest factor here.

also you do get the occassional dud that is so far behind anything else

heres a shot of one of mine at 14 days since sprouting

lol mine definately doesnt look like that. Not even the ones in soil of mine look like that. I have downed the ph a bit so I'll see how that goes. I also put my lights at full power. I think theyre old enough now. Thanks, guys.
