im feeding her tiger bloom. when they were in veg i gave them mg organic. its 5-0-0 when i started the tiger i stopped using mg. i flushed my soil today.Your fan leafs are going to yellow and die.
the spots on them looks like a phosphorus Deficiency.
Your plant also looks a little lacking in (N) also.
I would also suggest using Cal/Mag every month just as a preventative.
When have a feed her?
what are you feeding her?
Is your soil pH in range?
this one i only feed twice a week if that, the soil stays moist it soaks it up but does not get dry like my others. and to top it off i moved them to a diff location today and snapped a branch right off the stock. so i got that dryingflushing is for toilets mang just hit them light and dont over saturate the soil it causes worse problems .
tiger bloom is fine and would not cause this unless all your plants fed this way look like this... key indicator...
light feedings ppms based on size with time for soils to dry a little bit (day or 2)
