so your leaves in the veg room are going from 9 bladed or 7 bladed down to 3 bladed? That one I don't get. I can understand it if it's during flowering, it happens then. but not during veg.
Let me ask this, is it new growth that you're looking at? Sometimes you'll only be able to see 3 blades, but the others will develop given a little more time....They're just extremely small. too small for the eye to see right away..
