OK, Now that to me is way way too much, I would say your maxed out with the amount of netruents you can give, Now I feed once a week, as do most people, You need to try and take it easy with the netruents, You may have got away with it for so long as it looks like your growing out side, Back off a bit, try as most do Feed, water, feed, water, This makes sure you dont get a build up of unused nutrients in the soil.Some plants are heavy nutrient feeders, and some are quite sensitive to over feeding. Its a case of finding that balance, The YELLOW tips wont repair themself, but you can prevent it from happening again.Im off now for a tea and spliff, But i will be back in the morning, Im always will to help mate, so dont be shy, Have a pleasant evening, GBK

Its gonna be nute burn for sure as above and the main culprit would be the pk 13/14 that your using. At a "guess" they look about 3 maybe almost 4 weeks into flower. Cut out the 13/14 for now completely and water - feed - water - feed. As above, the yellow is not gonna go away on current leaves but if things are well then new growth will look ok. Everything looks generally healthy though from the pics.
