Sufractant

maybe it is, but sufactants are unnecessary additions to the foliar spray because the leafs are already at 80%+ nutrient uptake efficiency meaning less is more in the spray in any case. You're more likely to burn the plant than help it by cramming much more through those leaves . spraying is a good idea though, i do it even through most of flowering if i'm feeling brave/confident lol . You're absolutely ready to flip, keep her in veg another 3 weeks if you want to maximise her potential though.... Hope this helps ! 🚀
