With u
@Papa_T neem oil without knowing ur mix
@customwizard its hard to say cos some nutes are only meant for small amounts of foliar spray and to only use at certain times throughout ur grow period my friend ,but any nutrients u buy will have their own recommendations for when and how much to use as foliar (if it can be used that is) best thing to do if ever in doubt then whatever the nutrients feeding volume (amounts) are then do a little less and increase slowly to ensure if any damage is done u can quickly resolve and recover...all the best 👌
