My white widow auto flower are 6 weeks old. They are 4-5 inches tall with at least 3-4 levels of leaves. The plants have started to show sex with pistils in the nodes. Is this flowering stage beginning? I read when plants start flowering stage you should change To a 2700k spectrum CFL bulb. Should I do that? It just seems to early.
Yes it is flowering, you should switch to your flowering lights
Thank you is it best to change over in dark period
I usually do, I’m using an 18/6 light schedule too, also start changing your fertilizer from grow to a mix and then to flower. I usually take at least a couple weeks to make the full change
