Why leaves like that

I hope. Her leaves seem too tired. Should i take all those leaves which damaged ?

@Growstick quei fertilizzanti regolano il ph in automatico uso i sensi che sono un po' meno costosi di quelli.. io penso che sia la carenza che hai provato a curare un po' in ritardo quindi penso si sia fatta piu evidente.. per assorbire i nutrimenti ci va qualche giorno

Most likely a potassium deficiency, but this could be caused by the PH being too low rather than an actual lack of the K in the soil - I'm assuming that the AN Bloom contains more than enough K already (?), hence I think it's more likely a PH issue. Any idea what PH you're watering/feeding them with? You want PH 6.5 in soil.
