Neem suffocation. Mist LIGHTLY. And too much in the soil will change its properties. You put on too much, you clog the leaf stomata and the plant can't exchange gases.
There's no way to remove neem from the leaf surfaces; stop spraying it, increase air flow, and decrease light intensity until the new un-neemed growth is big engouh to sustain the plant. You will lose a lot of hte affected leaves. Also lay off on the nutes. You are tryin gto slightly slow down the plant's metabolism while it heals.
