IMO, I don't use molasses on the last weeks just at the beginning of nutrient cut off.. I do something like this;
Say you do a 3 week flush.
3 weeks to harvest - cut off nutrients, but I will still be feeding the girls with 1tsp-1tbsp unsulphered molasses per gal of water.
2 weeks to harvest - I might use some molasses (~1tsp for a gallon maybe a couple gallons), but chances are I am starting to use plain ro water.
1 weeks to harvest - I give the girls a huge flush at least 2-3x their container depending on the prior flushes and how big they were (I also like my run off under 50ppm before I cut). After that flush let them dry out abit and your should be good to harvest.
A trick I have found to work pretty well is the fan leaf sap tasting test. Pluck a fan leaf from down low and up top and give the sap a taste, if it is still bitter I would in fact give the plant another flush, if the sap is tasting very similar to clean water, you should be good to harvest. I do not know how on point that test is, but it has not failed me since I have started using it!
