syde, they all look like they are experiencing some rapid vegetative growth - really nice lookin' plants, bro! Let me know how your ph pen works out, as I may need to invest in one; I've tested input and runoff with a pool test kit, but am not certain of the accuracy due to age of the chemicals used. I have a few minor issues I need to address just to see livelier plants, and the ph pen will be a step in the right direction for me.

Thanks for the update - the pictures are awesome! I can't wait to see what they do in flower.
