first time growing and ive had some snags my plants seem to be slow gtowing which im working on but i seem to be growing more up than out. theyve been lanky since seedlings ive kept the lights close to them only moving them up when the lights were within a few inches. i topped them at 4 weeks an they seem to be doing ok but now the stem is getting thicker but only from the secondary leaves on up not down to the soil so heres my question - will they thicken from the top down or do i need to worry that this plant will get too heavy for the base?

Could be genetics, could also be lighting. Got a pic so we can see what you're talking about?
