Blimey 18 weeks? - i noticed u said from seed did you switch to flowering from the off? they were about a month old when i switched so they are really 19 weeks from seed- 15 flowering lol I take it you wont be cloning from that plant? lol.
Got 2 1/2 ounces dry of the LSD's so hopefully if they do go to 18 weeks ill have enough smoke to keep me going lol
