I checked the plants today and so far 7 of the 9 lowryders are female, 1 male and 1 unsexed. Out of the other bigger plants; 2 out of 9 are female and the rest unknwn. Some of the plants are still pretty small but i couldnt be bothered vegging any longer so i changed the light cycle to 12/12 and began flushing the plants. I also bought some cheap fertiliser in the garden centre, i think its 9:21:12.
