Whats wrong with my plants? -PICS-

Hi, this is my first grow using bag seeds. 15 seeds > 11 germinated > 10 sprouted.

14th day since they sprouted.

Using:
12/12 from seed
Soil Biobizz all-mix
150w hps @ 8 inches
0.75 L cups
Water with biobizz Root Juice 1ml/L
Temps with light @ 25ºC - 40% humidity / Dark less 8 or 9ºC (pretty low) 80/90% humidity
Using tap water without checking ph (i think its ph 7) - Let it rest for 48h

So why do i have 6 plants looking good and 3 stunted for 1 week and 1 with very little leafs?

I water them 3 times including when they went to the dirt. I even let them 7 days without water just to make sure they were not overwatered and to see signs of thirst.

Thanks.

Just genetics. All look healthy to me. Some are just slower then others. If you want to, clone the healthiest and fasting growing girl

just grow the Healthy Vigorous ones....Survival of the fittest!

6 good out of 10 sprouted... that's about how it goes. Select the best, reject all others.

Thanks a lot for the quick reply.

That was what i taught, since they were bag seeds, some seeds look very small and very light color. Thats the reason i germinated all of them.

Since i just have a 150w hps (thinking of adding 4-23w CFL) im gonna stick with those 6 that look healthier, if i get 3 females its perfect.

youre good to go for sure. like everyone said, ditch the junk ones and baby the shit out of the others. good luck
