Long Darkness before Flower?

so i heard that people put their plants in darkness for a day or two before they flower them. i did that for 2 days and on the the third set them into flower. i noticed that they had faded much in color in the tops of the plants and in their new growths. i put them into flower and the light i had stopped working so they were probably in darkness for another 12 hours! thats almost three days! with some light. so today i replaced the fucked up light with fluorescent lighting and everything is back on track, the leaves are still faded a ton so what should i do? i have started giving them flower nutes so idk what else to do! if anyone has any ideas let me know!

Give them some grow fertilizer (more N), start them out on a 14 hour lights on schedule with 10 hours off. After a week, drop to 12/12 and you will be fine.
.
In the future, keep it to 24 hours lights off (maximum) before flowering - anything over that is risking trouble.
.
Hope this helps...

I've tried the no lights for 1, 2 and 2 1/2 days and found - all the plants I grew - responded better to only 1 day with the lights off.
.
Does this cause hermies by itself -NO. If your plants genetics have in them a hermie trait, any stress over a long period of time will make the hermie trait show it's ugly head.
.
No light for a day, is not long term stress - It is no different than when you have a seriously cloudy / rainy day. But in nature, seriously cloudy / rain days, seldom last more that a couple of days. So, play it safe and keep it to one day with no lights, and only on mature plants.
.
The whole ideal behind the no light for a day thing is so that Mary will build up a slighly higher level of light sensitive hormones that promote flowering. These hormones are reduced or weakened by light, until the plant is mature (has finished a proper veg cycle or with clones (have proper roots). After a plant is mature, the rate of production of these hormones increases, so more are being made, than destoryed by the light.

your all wrong, i often put them under 48 hrs of darkness when begining to flower this speeds up the plants by a week so if you got a 9 week strain it will finish in 8 btw when doing this you should feed folvic acid this is why the tops of the plant go yellow cause they stretch and nutrients arent processed very well while in darkness its not a nitrogen deficiency.advanced nutrients f1 should do the trick.

The darkness period i heard makes your plant show its sex faster. I heard that it resets the internal clock

I did not know it was possible - for all of us to be wrong.

You must own a copy of the Grow Bible.....
.
I'll put my thirty years of experience growing Mary, up against the fairy tales told in that book any day. Jorge has an agenda there - promoting his books and high dollar fert companies - soil, grow mediums and three part nutes.
.
All plants have a gentic traits - growth habbit (vertical / horizonal), bud development / leaf ratios / size, THC levels .... etc... it's genetic - flipping the lights off for two days is not going to rewrite the DNA of a plant nor is buying some " Miracle in a Bottle" for just $ 49.99
.
The lights off for a day, helps set the change from growth to flower - it does not speed plant finish times - " That is just a Fairy Tale " - believed by those with more books, than experience.
.
Keep it Real - as in Reality.......
