🍯⚗️ Old-school molasses vs new-school PK boosters — and why the answer is yes to both.
Nik says a plant's sugar levels are one of the most powerful levers you can pull, and the old-school "feed your plants molasses to bring out the flowers" trick isn't wrong — it's just half the story. The newer reflex of dumping phosphorus and potassium (PK) into flower isn't a competing theory either. Both camps are pointing at the same thing from opposite ends.
Here's the link: plants don't actually use plain sugar to build things. They have to attach a phosphate group to it first — and that's the actual building block the plant uses to make terpenes and cannabinoids. To form these the plant needs phosphorus to supply the phosphate, and potassium to move the sugar around and switch on the enzymes that do the work.
Run short on either and it doesn't matter how much sugar shows up — the plant can't use it for flowers and ships the carbon somewhere else entirely.
Practical takeaway: Sugars and PK aren't competing strategies — they're partners. Keep PK sufficient (not maxed out) and the whole sugar-to-flower pipeline stays clear.
