I need help guys I’m new

[Repulsive]

Hey guys I’m new to the whole growing thing and I’m just trying it to see how it goes so far I’m enjoying it but I ran into some problems, I have two plants auto fem and one of them has thick and nice leaves and the other is growing really skinny and thin leaves. I had problems with that exact plant due to it getting to much nutrients even though I didn’t add any yet. Any ideas on why it’s growing so skinny picture is added. I’m from Australia btw so my growing conditions are different and it’s hard to find much Info about growing in Australia. Thanks

Are both plants the same strain ? The one with the fatter leaves looks Indica & the Skinny leaves look sativa. Sativa's grow taller & thinner than Indica's. They look fine to me. Might want to LST them to keep them short & bushy.
