week four flower nute problen

So i am growing in soil usind advanced nutes hrow micro and bloom every other feeding. Use big bud bud candy overdrive and voodoo juice. After last feeding i jave noticed the oldest lowest leaves turning brown on edges and feel dry spreading up. I flushed all plants to checl for salt build up here are some pics. ill take more if anyone needs more

Any input will be greatly appreciated.

You over did the bloom nutes.. just use ph.d water till they come around. I only feed every third watering...

I appreciate it sir. Greatly.

Thabk you again. When using an with soil do u use at quarter strength or half

I never really used the an line.. but with gh.. half strength every third watering..
