Hello, I am growing for the very first time and I have four plants that are under 6700K CFL bulbs. I currently am running them on a 20/4 light schedule but I I'm not sure when I should switch them to 12/12!! I'm attaching pictures so if you could look at them and let me know what you think, that would be AMAZING!! They're all about 8 inches tall so I think I might still have a little ways to go, but if you could let me know what I should be looking for and at what point I should know to switch them? Also, ALL I have to do is switch the lighting to 12/12 and the bud will start to grow, correct?? PS- The leaves are kind of brown because I went away for a weekend and watered them too much so I got fungus gnats and had to put cinammon on the plants/soil to kill the bugs. THANK YOU!!!!!!
