man, afore you do that, just cut the biatch down and throw it away. veg ur good plants longer and clone those... or you'll be stuck with a whole crop of stragglers like the one you don't want to flower now.The plant looks healthy, just lanky. Its just not doing much. There's actually 4 plants under my 600 MH now and thats one of em.
Im gonna cut it up for clones, not worth flowering. Here's a closer up pic of the 2 plant. The one in FF made it to the flower room today. Anywayz, it is what it is.
