Why leaves like that

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

@Growstick those fertilizers automatically regulate the pH, I use the sensors that are a bit less expensive than those.. I think it's the deficiency you tried to fix a bit too late, so I think it became more evident.. it takes a few days to absorb the nutrients.

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.
