Hard to say without knowing all the conditions - but it looks like too much nutrient, or improper pH. I'm not sure on either of those - but would flush the plant with lots of pH adjusted water at 3x the pot size, then resume light feeding at next irrigation. Hope she turns around!

I've fed them only with GO bioroot at two watering. But nothing changed. Can ı give them bloom nutrients now?

My first thought was nitrogen toxicity, as the leaves seem to be curling under, or "clawing". Your humidity seems ok, as does pH. You may want to verify/calibrate your pH meter just to be sure.
