has anyone ever used sulphur in the flowering phase, if so what was the method? as i heard this improves the terpene profile but yet also kills bacteria! is foliar feeding the best option for sulphur uptake?
foliar feeding is the best for any uptake , absorption is 80% efficient through the leafs and only 20% through the roots, so you should be careful while making your sprays, but theoretically anything would be better through the leafs even NPK etc.
