If you are looking to sex your plants, DNA sex testing is pretty cheap and honestly the best way to go about it if you want to save time. In fact it has become a very common practice in the industry. Farmer Freeman is $15 per a single test and cheaper as you buy more (10 for $120 and so on). Delta Leaf Labs is $10 for a ten pack of test kits but the testing costs an additional $9 per plant (or 10 for $100). Phylos has test kits of 4 tests for $60. There's others like them out there and at $10-$19 a plant, it will save you hundreds when looking at your time, energy, and materials you would have had to invest waiting for the plants to mature in order to flip and find out the sex. You also don't have the risk of screwing something up flipping and then reverting your plants back to vegetative growth, as you plan to do.
