I read that when they go into flowering and are more mature, the number of blades will start to go down.

That was in my 20 year old growers guide. Hope it is the truth.

I wouldn't worry unless your plants start to look sick. :thumbsup:
pepurr Reviewed by pepurr on . why did it go back to 3 leaves? The set-up i have is two plants, with 2 -75 watt flourescent tubes. the 2nd tube was just added, and before that the top had 5 leaves, now that the 2nd light is there, the top is back to 3 leaves. why would this happen? Rating: 5
