Hi
They're definitely suffering from nute-burn (too much nitrogen), and possibly a calcium deficiency.
You need to flush your plants by pouring water 2-3x the volume of the pot or until the run-off water is clear.
Adding too much nutrients and having an inadequate pH will case some of the micro-nutrients like calcium, magnesium, iron, etc. to be locked out from your plants.
Have you been checking the pH of water and feed?

yeah,I've been checking the ph but just when adding nutes!,i keep it from 5 to 6.5 using the drops,but i'm using distiled water,should be out of minerals?,

a pH of 5 is way too low.
Distilled water contains no minerals, so that's what's causing the calcium (and perhaps other micro-nutrients) deficiency. You can fix this by adding dolomite lime, black molasses, or what I use is this powder called Alkabase which contains most of the minerals required by both plants and humans
You still need to flush though. There's definitely some nute-burn there!
