the stems do look a bit thin and ya they look small for 2 mts, if they are auto's then maybe they have started flowering, however they will still continue to grow, try tying the plants loosely to a strong upright stick to prevent them breaking, don't overwater this will vastly reduce growth, just stick your finger into the soil about an inch down and if it comes out clean then water but if soil is stuck to your finger then its ok for water, also i dont see perlite in the soil i would advise repotting into a 70/30 soil/perlite mix the roots need oxygen and perlite helps this, try get better pics if poss and i could give u further advice, there's no such thing as a dumb question only dumb answers so ask away and i'll answer best i can :jointsmile:
