Your plants are looking amazing! Well done for sure. I'de start adding molasses now. I add a tablespoon per gallon and use it every watering. You should prolly add bloom nutes as well. I'm not really one to recommend brands as I only have expirience with what I'm currently using. Here is what I do - keep in mind that most probably wouldn't recommend my approach:
I keep three separate watering containers - Veg has vigoro all purpose plant food 24-8-16 diluted to 1/10 strength, flower has flora nova one part bloom 4-8-7 tbls per gallon along with 1 tbls molasses, and the third container just has molasses. I am growing multiple strains which develop differently from eachother so i customize each watering. My plants will either take 2 cups water every day or 3 cups every other day - i prefer the everyday. So when I water I mix the three mixtures depending on the plant and its age. I generally start with just veg, then half veg half flower, then just flower, then half flower half plain molasses, then just plain molasses. I use my nute mixes every day and flush every few weeks.
