Hi, about 7 weeks in my critical kush has overnight turned yellow on tops of leaves.. more like small speckles covering fan and sugar leaves.. I think LED light burn?? 2 other plants not affected but under diff LED. And NO bugs..?
I have inspected the undersides are normal green. A few days on and the yellowing is crispy and dying.. seems like nute burn and sunburn in one. Dimmed lights n flushed, starting to look.. ok
Hey mate,
Have a look at the bottom sides of the speckled leave! Take a magnifier and see if you find small black dots. Looks to me like spider mites..
Servus
