Stickanswered grow question 6 years ago Well it's hard to tell because we can't see pictures of your burnt leaves or the plant in its entirety. What is the ratio "healthy leaves / burnt leaves" ? Since when have you noticed yellowing ?
From your last photos, I see healthy plants which should finish flowering with no main issue. Remove the dead leaves in order to reinforce air-flow and light penetration and keep up the good work with this beauty !
