Sorry to be a pain but if Gave them fish bone and blood fertiliser will it be okay to give him this NPK
NPK is what you've already given them, that's what is in fish blood and bone, what you haven't given them is the trace elements.
BUT, as Yorkie says, wait a while and see if what you've already given it does the trick, before worrying about anything else for now, apart from water if the weather stays dry
It won't hurt the plant to lose those a few leaves....
