Second cannabis grow, four plants

[Dopeman2]

Growing 4 amnesia haze photos. This is about 2-3 weeks after germination and the two bigger ones look great. Just transplanted them. Why the others ones so small?

Few reasons for this. The biggest to be seems to be genetics. Seeds seem to express variables in presentation. I ran white widows and out of 4 plants I had 2 identical and 2 others that looked like different strains. The Apple Fritter autos 10 days above dirt already look different. Just genetics.
Second is environment. Air blowing directly on 2 plants and not on 2 plants or a light pattern weak on 2 plants strong on 2 plants.
At this point watch your watering. You should have 2 different watering techniques with plants that far apart. I would also pot up the last 2 to make it easier.

I’m a little worried about potting up bc the bigger ones have been growing so slow this past week. I’ll send a pic this was last Friday

Are they bag seeds or bank seeds? Most likely genetic like Jim said. With bag seeds the genetics are all over the place sometimes, theyre not breeding them properly thats why theyre cheap, when they get out of control they just run new seeds from a bank. Theyre growing nicely. Slower after a transplant is normal, but they are growing and it should speed up after 1-2 weeks of the transplant depending on how healthy they are, they look healthy. At this pot size range the pot will greatly influence in the yields so I would transplant them without a doubt. With big pots at some point it doesnt make a big difference but with small pots it does.

I have them in these plastic bags temporarily u till I transplant them into 10 gall bags. I just wanted a smaller pot to move them in and outside
