Hey Luan, seems to me this is more like a potassium (K) deficiency. Check if the signs show up at the top or bottom of the plant, if top then its probably a Calcium (Ca) deficiency since it is immobile, and if it's at the bottom then it's a Potassium deficiency. Either way try increasing the bloom and micro fertilizer dosage to about 2.5 ml/l (0.5 ml/l increase). Also remember to check pH and temperatures regularly to make sure your plant can even uptake those nutrients!! Hope this helps! good luck and happy growing :)
