So I've noticed some of my plants starting to get a yellowing around the leave edge.
(See photos )

Not all the same cultivar, but can see similar effects around it.


They get ph 5.8 water all the time.
Organic nutrients (Bio - buzz) every second watering ?

Under 600 W MH.

Temps are at a stable 28°C give or take a few depends on the day.

Please help View attachment 4310789 View attachment 4310790 View attachment 4310789
