Hello dear fellow growers, I need your expertise.
My plants (white widow) are 5-6 weeks into flowering, and now very suddenly developed both yellow markings and especially wilted, brown leaves (see photos). It came extremely quickly out of nowhere and on all the plants in the growroom. On each, only the top part of the plant is affected, further down they look healthy (see last photo).
The lights (600W LEDs) are at about 20 cm distance from the top. I use the T. A. Tripart nutrients and have upped the amount lately(a bit higher than what's recommended on the bottle), could it be a nutrient burn? Do you think it's the same problem (wilted leaves/yellow markings) or two separate ones? (I'm more concerned about the former, it's much more prominent). What else could be the problem?
Growing in soil (parts perlite and coco coir)
600 Watt LEDs / 12/12 light plan
pH 6.4
Watering every 3 days with 10+% extra runoff
Thanks for any tips and happy growing!
