no I would never put them in the dark for that long between veg and flower. That just creates stress. Farmer john fourtwenty made that popular because he does it. If you watch his videos you can tell he doesn't know shit about plant lighting and feeding. very redundant nutrient line... anyway thats bad to do imo. That never happens in nature. Recreating nature will yield best results. I put them in the dark for 2 days right before I chop though. Calyx swell up more and 2-3 times the resin production.
with lighting schedule it all depends on strain.. With sativa dominant strains. I'm sure
14/10 13/11 will work fine but not for indica doms... My veg is on 20/4 in 10 days they will be transplanted into 7 gals then veg 20/4 for another 4-5 days then drop to 18/6 for 4 - 5days. Then 14/10 for a few days then gradually drop to 12/12 over a span of 7-10 days. By the start of week 3 they will be at 12/12. Well anyway that's my plan for the next batch.
In all honesty with pfr IR led and what not. It's all trial and error. Like I said there is no definitive answer. It's all strain dependent.
