Robs World leave end questions

Just wondering im starting to get droopy leave ends lights are 18in from girls temp 80 at the high 68 for the low 50 % humidity any thoughts? I think they look great anyway

First I would check three things: bugs, heat/light stress and under or overwatering

No bugs waiting until the top inch of soil is dry before watering raised the lights and it helped thanks

that "top inch of soil" thing is incorrect so you probably got over-watering going on which has probably thrown off your soil pH which could be why the tops of your plants look like that, how often are you flushing out runoff and what have your recent runoff readings been?

Edit: also why are you sure you don't have bugs have you checked? Thin twisted New Growth can often be an indication of mites
