In my experience switching back and forth between flowering and veg slows things down. 7 inches might be a bit young for the preflowers to show naturally, depending on the strain. If you wait a bit longer and get a few macros maybe you can spot some pistils.
SupraSPL Reviewed by SupraSPL on . Light Confusion, URGENT!!! My plants are almost 4 weeks old. They are about 7 inches tall. Doing really good, very healthy. From seedling to now they have been under 24/0 light. I was told by a friend that I should cut back the light for 24 hours starting now. check them in 24 hours and if there is no sign of sex then cut it again for another 24 hours and so on until they sex. After that they said to put the light schedul back on 24/0 then to 12/12 before harvesting. Is this good advice? Or will that do damage to my Rating: 5
