Noticed this morning that the tips on one fan leaf is curled down and is crispy this has happened in the past 12 hours, only seems to be on one leaf out of 3 plants, sprayed with bug clear ultra yeasterday at lights off to get rid of thrips
Probably got a large drip that rolled down your leafs and then sat on the end and got heated by your lights. I wouldn't worry. The girl looks super healthy and happy! Cheers!
