answered grow question 6y ago
What I would try first is to bring the ph down to 5.5 - 5.8. The 6.7 its at is out of range for dwc and proper uptake. Good luck

Brown spots on the leaves
Hello, everyone. After replanting, this appeared on some of my flowers. I think it's probably stress after replanting, but I'd rather ask you more experienced ones. Thank you in advance for the advice 🙂

What nutrient deficiency is this?
What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

What to expect when your plants have been sick in veg ? (N excess, chlorosis)
I had a nitrogen toxicity and a chlorosis (overfeeding, bad PH probe) during veg. They are green for a few days (Now day 66 from seed and flowering since day 41). One has messy and 2many leaves, one burned, 2 are small. I was wondering about the consequences on quality and yield?
