Amending supersoil with potash


Hi yawl, should I add a handful of potash to my supersoil? Was told by store not to but I dunno!

This current grow, I have one plant that was showing signs of potassium deficiency in flowering so I’ve been adding small amounts of potash. If there isn’t a deficiency don’t add it… it can affect the plant’s ability to uptake nitrogen (which in flowering isn’t a big deal).

Depends on the reasoning I would say. Potash isn’t the only source of potassium either. You could easily raise potassium availability through top dress and/or teas.

If it’s straight up pot ash from a fire place
A hand full will shoot your ph through the roof.
