I have an AK47 and Bigfoot that are both showing a good amount of pistil growth while on a 18/6 light cycle. I also have a White Widow and a Northern Lights, both that aren't showing pistils. Why am I getting pistils during the veg cycle? Also the AK-47 and Bigfoot are grown from clones, where the WW and NL are from seed. The AK and Bigfoot are both a foot tall.
