Honestly, I’m waiting for my ph up and down kit to come in do I’ve been strictly watering dechlorinated tap water. I’d assume it’s that but any input is appreciated. I got two 300w vivosun lights at about 30” about the canopies. I’ve got five plants and all of them except for this one look great. R/H is roughly 70-80%, temp is roughly 20-29C. Watering only when dry. Thanks!
