Light Schedule

Keep at 18/6 it's perfect for autos, if you change the light schedule they won't get as much light as they need to reach their full potential which will hurt you at harvest.

you can let things go on 6/18, they need a lot of light to thrive their time is short as to 12/12 (it is intended for photoperiod plants there is no need just let them do it alone they don't need a photoperiod to flower "would bring delay and a change of menas light in the period that needs most in fact the car fits well in 20/4 and this period is enough of rest to produce what you need to get in bloom what you are using and the most popular 18/6 bringing results proven, an option would be to enter some more "nutrients" for flowering your leaves are clearer, lime-magnesium, algae, bloom mainly if your soil is "semi-inert" without compound nutrients but still a balanced demand for nutrients good wish luck at all!
