Been on 12/12 for 15 days now, and only 1 of five plants has preflowers. Checked for light leaks, and thats OK. What else could stop them flowering? Giving them weak bloom fert twice a week and that's about it. Growing with a 250w... Any ideas? easy....
I've had plants that took nearly three weeks to start flowering. I can't tell you why but maybe it depends on the strain.
