Hey guys my two bruce banners are looking pretty bad at the moment All the bottom leaves are drying up, curling and yellowing or browning Could this be nute burn? Or even from fungal gnats? It seems to be getting worse and coming further up the plant
The even paling/yellowing of the lower leaves is a sign of nitrogen deficiency. I don't see any signs of nute burn. Add a bit of extra nitrogen on your next watering/feeding.
