Im not sure if using the bud factor x and candy will conflict with each other. I havnt used them so... I recommend bio bizz top-max. This is a stimulant which aids in sugar and water transportion, increasing no only bud size but more bud sites. Thats from my tests, using for one not for the other. It has full range of macro and micro nutes,is in lquid form to aid dissolving/mixing,and works.
I use that and Bio bloom, also bio bizz, in flower. They are organic, resonably priced and work. There are so many flowering ferts and stims that I would advice a fert for every 3 days and stim every day. Just depends on what the manufactors says if it can be used together or sepreate. The top max and bio bloom work better independtly(apparnetly).
I emailed bio bizz with questions and they not only answered my question directly they took the time to explain how, and why it helps. woth plenty of product info.
Id just try and see with a dilute mix and work up to full doze. Hope that helps
