The bottom leaves are like that cause of all the growth towards the top. Look at how big the leaves are on top. Not all strains grow the same. How can you compare one strain to another on how it is growing? I just looked at my girls right now and the one your talking about has reacted to the additional light extremely well. On the pic your talking about, its Afghani. Look at the leaf formation. Some stems only have one leaf finger on it. Another reason for the leaves to be smaller on the bottom is that i did not top this girl, nor the rest of them. Not yet anyway. The concentration of growing for Afghani is on top. Reason for the leaves on the bottom to be smaller. I have not pruned them either. I am waiting a little bit more, then i will take clones (the bottom smaller growth). Hey i am still going to do what i have been doing. I will keep posting and you will just have to look out when i post on what my yield came out to be............................. Oh yeah, one more thing. All the leaves should feel dry to the touch as i don't mist them and water or any moisture doesn't get to their leaves....
