One of my plants has started getting brown spots, the leaves are curling up and crispy around the buds. Only one though? pH is 6.0 Coco coir Week 10 northern lights Auto Watering every 2 days with 20% runoff. Is this calcium related? I have been supplementing calmag the whole grow Thanks
How big is the pot? Do u have perlite mixed with your coco? How close is your light? What’s your temp? Do you have a fan on the plant? Why aren’t you watering daily?
How big is the pot? 5 gallon fabric Do u have perlite mixed with your coco? Yes, about 40% How close is your light? 20" 600w vented hood What’s your temp? Room temp is 70f, canopy temp is 80f - RH is 50% Do you have a fan on the plant? Yes, 440cfm extraction and 2 intakes (still have negative pressure) and an oscillating fan across the canopy top Why aren’t you watering daily? Because it stays very damp and I've had a few fungus gnats
Not a coco guy. But I read alot of posts that do. Sent from my SM-G935T using Grasscity Forum mobile app
So I thought in Coco you pretty much water and fed everyday I'm thinking your pH might be a tiny bit High maybe I'm wrong. I would think maybe you have a little pH problem going and obviously the old Cal mag issue. I'm pretty sure you need a lot of that growing your style wait for the experts in Coco Sent from my SM-G935T using Grasscity Forum mobile app
