why?

i started with 4 plants i just had to pull a heme...down to 3.... 2 of them are nice full healthy 1 ft plants. the last one is a stragler, only like 3 inches no y branches, yellowy colour.. how is it possible to have such a deference under the same conidions??? i relize they will grow at deferent rates but shit

the genetics?

There are always a few runts in every garden

If it is outdoor, there are millions of factors that produce intermittent results.
If it is indoors, it could be sick.
