@osa28 : Does the 1 ML per Gallon need to be applied starting at flip, or before flip? Can I line it up so the last of the 3 feedings are on flip day?
Got a run of GG4 / C91 I wanna try and keep squat.
You can run at higher dose as any time to encourage a more compact plant. It is NOT a PGR so it won't work on every plant and in every situation. If you are running an intense environment like high CO2, temps and low humidity, not much will slow vertical growth. Also, a single application with no prior use will not likely have an impact (I think this was why @DemonTrich didn't see results). Silicic acid is most effective when it is fed continuously in small amounts, especially from early veg. Disclaimer: nothing works in every situation.
