Gundari I tried to download your pics but could not.....it may be a problem with my dial up service...don't know but can't get a close look at the new leaves but will take a guess that perhaps you are now OVERFERTING.

Read this post carefully and it will explain how once you fix your ph you suddenly can have a nute burn problem. I'm just guessing (can't see pics sorry) but give this a read through and see if it makes sense to you.

I would stop giving any new ferts until you figure out what going on.
