They look more like 2 weeks into flowering. A shitload of crappy low watt lighting enveloped in tinfoil does not work as well as a single high watt grow light. It's also grossly inefficient; you are pulling down a lot of power for very little output. Running all those lights together is also adding excess heat and needlessly.
Ditch those cfls altogether at this point. Cfls are good for vegging seedlings or very small plants/clones but they are probably just adding more heat than anything else. The reason you need to tie them all kind of ways is because they were vegged under low wattage and got too lanky; too much space in between nodes. You want tighter nodal stacking so your plants will grow nice long fingers of bud later on.
A lighting upgrade would help your grow a lot. I suggest getting at least a 400w hps or equivalent decent quality LED; wattage is what drives bud mass. Lose the foil and get either panda film or build "walls" out of plywood and simply paint them flat white. Also get some good airflow on your plants with say an oscillating fan earlier in their development so the stems get nice and sturdy to support the heavy buds later on. To answer your Qs: yes the buds can and should get bigger but without higher wattage lighting the final bud size is severely limited. You've got another 6-8 weeks at least maybe even much longer. Finishing times go right out the window with insufficient lighting.
