You can do it but to be honest it's a total waist of time because your Veg nuts will not contain enough elements to achieve a flowering so you'll have deficiencies BUT you can still harvest something , not the best taste because of the high Nitrogen amount, not the best weight because she'll run into deficiencies and not the best consistency and I bet on a fluffy/foxtail weed BUT you can do it. The better thing to do is to switch from veg nutrient to bloom nutrients except if you have a formula made for growth and bloom ( you can find some )

I am feeding 2 time then 1 with plain water and I am repeating , I like to keep my nutrients level at a good level as my pot are often 5 to 10L pots and the plants are gerting rid of the nutrients quickly so I have to bring some regularly. Generally in soil grow the mainstream advice is 1 watrering with nutrients then one with plain water and repeat A dry wet cycle seems better to avoid watering issue but if you can't then be easy on the watering , lift the pot to water at the proper moment and not too much. I can't give advices on a watering frequency in soil as it's the oposite of what I am used to recommend
