You have leaves that are a little too dark green along with some leaf tip burn, both indicating that you have "fert burn;" too much fert has been given. As far as splashing fert on the plant goes, do you think this is possible? If not, then you need to consider something else. I doesn't really look like that as I've done that and can say it looks more like a nutrient problem right now more than anything else. You gotta go easy on these ferts you can buy in a hydro shop, meaning try not to feed to often. It might not be necessary.
