Yep, he is still in veg, based on what he said anyway; "Well, I'm ready to flower, but I've got a couple plants that are about out of room in their 3gal pots (well, bags). can I go ahead and flower
You don't need pictures to tell him he shouldn't re-pot in flower and you don't need pictures to tell someone how to deal with height issues. Do you actually need to see the plants before you would then be able to know how to deal with them? Hell no. Height is height and how it's dealt with is not going to change regardless of seeing pictures or not. If you cannot correctly tell someone how to deal with a height issue without pictures, you wouldn't be able to correctly tell them if you did see pictures.
It amazes me how an extremely common response to even the most simple of questions is post pictures, post pictures, post pictures, pictures would help, pictures would be nice, etc. They just are not needed in some a good number of cases, but yet they are very, very, very often asked for anyway.
At the increased rate I have seen pictures asked for in the last few months or so, when they were in no way needed and would not be at all helpful to anyone who knew what they were doing/talking about, at times I almost wonder if it's because some people here want to collect information/evidence on others.
