Epsilon F1 (RQS)

This week started with a flush because of a mild nutrients burn, or so it seems. Gave them only water for three days, then nutrients every other day. Looking at trichomes last night, harvest is coming soon, as I can already spot a few brown ones here and there. I'll probably keep feeding them phosphorous-based nutrients on and off for the rest of the week, then plain water until harvest, be it in a week or two. Quick question, if someone read this : Would switching back light schedule to 18/6, or even 12/12 be advisable for autos starting flowering stage, or a few weeks later ? I'm wondering because of the hot temperatures and energy bills, though no biggie. I think that's it; have all a nice week !
