I'm in dwc ph 5.5 ppm 400 week 4 of veg I thought at first it was the light so I turned it down to about 250 ppfd then I still got it so thought I was overfeeding so gave them less nutes did a bucket change still happening wtf can it be from low humidity ? Temps 70s humidity in 40s tips burning curling upwards looks still like bleacching but the plants is getting more then 300 ppfd
