Hey bro! 👋
No, don't touch the leaves, the plant will drop them when it no longer needs them!
These leaves are a result of your excessive feeding with nitrogen and phosphorus, plus the unsuitable soil acidity!
The acidity should have been 6.3 pH for soil at your flowering stage.
bio-grow 1 ml/
bio-bloom 4 ml/l
Do this, and the flowering will go faster and without problems! 👌
Good luck, bro!
