Leaf structure

To answer your actual question, even though the seeds may be the same strain there will often be different expressions, even early on. When you see conversations about phenotypes this is what people are talking about. Usually, people are more concerned with things like the buds, but phenotypes can be expressed by just about any part of the plant. On top of that, sometimes even very slight differences can lead to differences. If you're interested, you can check out my Blue Dream Auto grow that I've got going on right now. The two plants are very different, even though they are both ILGM Blue Dream Auto and were started at exactly the same time with the same growing conditions.

How old are they. They look to be normal. Just please don't spray water on the leaves unless the light are going to go off. It can burn the leaves and dry them out. They look young tho 12-16 days ? So theyll bounce back if they are some dry leaves. I'm a noob too, this is just what I learn

What do you mean? Whats wrong with it? Do you know what strains they are? The only thing I may see wrong is over watering. That soil looks extremely soaked. Then again i have a cracked screen and cant see to well

wayyyyyy too much water my friend :) though everybody does it to begin with just let them dry out and then when watering only water around the base of the plant until you see any water come out the bottom stop do not saturate the whole medium in water it will drown your plants and open up doorways to all sorts of nasties that like damp places to hide and then eat your plant hehe just a little less water my friend and you will be golden.
