Waaaay over fed/ nitrogen toxicity.
Give just plain water for the next 10 days, then when you start feeding again, half strength of what you have been giving should be plenty.
Sativa dominant strains like Hazes need a lot less feeding than your average indica dominant hybrids.
Die Pflanze spülen und den Topf nach etwas austrocknen mit 30% Dünger pH 60-65 gießen wichtig erst wenn Sauerstoff an den Wurzeln ist. Danach müßte es ok sein. Viel Glück
During the flowering stage, those clawing leaves and tips are a symptom of a Nitrogen excess.
I won’t recommend flushing in flowering. You can pour a bit more water to get some more drain out of the pots and rinse a bit of the excess.
