Everything’s been going great until now - Help! Have no idea what’s wrong!
I started seeing a little tiny bit of tip burn & some yellowing on lower leaves 2 weeks ago, so I suspected a bit of nutrient burn & watered with only distilled H2O twice a week since then.
In the meantime, flowering started & 2 days ago started seeing the leaves getting yellow spots & added a pint of 1/2 strength Bergmans Flower Food/distilled water mix after watering with distilled water.
This morning, spotting greatly increased & seeing tips curl upwards in addition to more tip burn.
The other 3 have a few lower leaves getting yellow, but I didn’t add nutes yesterday like I did with this one.
Any suggestions to fix this?
