Hi, im growing 6 Northern lights at the mo, all girls, 1 of them, is untopped, and extremely lanky, also seems less developed, if it takes longer than the rest of the plants to finish, it will interfere with the next lot, which are already seedlings now, what i want to know is, when most of my plants are done and cut, can i leave the other plant which is well into flowering now, 5 weeks flower, can i leave it in thew room with the new plants when the lights are switched back up to 18/6 for vegging the new ones. Will it ruin the plant, or does a cannabis plant have a sort of point of no return where flowering is concerned, do u think it will finish safely???
