I wouldn’t do a big flush personally as that will take out any nutes you have in the soil. What are your watering practices, as in how do you decide they need to be watered? The burnt tips can sometimes be from letting the soil dry out too often, from light levels being too high or over fertilizing which it doesn’t seem you have done. The hard thing is I’m not familiar with the soil your using and it could be hot and that’s what is causing the burned tips. Is the soil like a water only super soil supposedly by chance?
