What's up forum, I have one Northern Lights XTRM growing under a 300w mars LED and a 90w Bloomboss UFO LED at around 20" from the plant. It is around 2-3 weeks old and growing very slowly. I water when the soil is dry. Temps range from 77-85 degrees, humidity between 38-70% depending when humidifier runs out. Too me it looks like heat stress and some kind of nutrient problem. I have only fed bottled water. Should I start giving it nutrients? Any help would be greatly appreciated!
This is odd to me. It looks like a nutrient toxicity, but if you haven't given any nutrients yet, what type of soil are you using? Sent from my iPhone using Grasscity Forum
I am using Happy Frog potting soil. I just switched from ffof because I kept burning seedlings a week in
