|Cut them off as soon as they look bad - it's a judgement call and it's up to you just how spent they should be|
If you see new buds forming, you want to cut above those to keep them. If you don't see any new buds, you can cut right above the top leaf (I go right above the top 'full' leaf and remove those tiny baby leaves right next to the flower).
|I cut above the first big leaf and remove those puny tiny leaves closest to the flower. If you see buds, always cut above the new buds|
|You are the weakest link, goodbye!|
