I topped it for the first time in the first pic and the stem is prob a bit bigger than a 1/4 inche thick but i can't even see the stem unless i move leaves around. I am also wondering if the top leaves should be that big. i have another plant prob 2 inches smaller and not near as bushy.

Here are some pictures of the other plant (Red Dragon). I bent the top off on this one because i seen a video that said bending the top off is FIM and it is easyer on the plant. Is this right?Attachment 287693Attachment 287694Attachment 287695

Are the stems suppose to be purple like that? I notice both my plants start with green stems then they turn purple. Could it be to cold? I keep it between 72 to 73 at night and 73 to 77 day time.

temps are not the cause of the purp its caused from a potassium def. which all purp strains have but only into late flower its nothing to worry bout its a good looking plant and you gotta think each leaf is like a solar panel you cut them off your going to shock the plant and lower its energy production which will just slow it down only time you should thin a plant out is when the leafs are dead or are shading other plants and also when they are in flower and you have poor air circulation
