Hello I'm a first timer and have a 20 week old auto that started growing pistils but also kept and still is growing new sites and leaves. The seed is supposed to be 'OG Kush' from 'FastBuds' and is on 18/6 of a 100w ( I know ) , in a 50x50x100 hydro tent with decent airflow and thus far only fed Scottish water which is a ph of around 6.5. I read a few forums and the like and found a lot of people realising they have the wrong seed or a seed that isn't auto. I changed the light cycle to 12/12 24 hours ago and now she looks weak as apposed to the usual stong stature and praying leaves. Any idea what's going on here ? The attached pictures are from just after 12 dark and 12 light.
