What’s up guys. I can’t figure out why my fan leaves are crisping on the ends. I’m in organic SoHum water only soil. They are about 3 weeks into veg. I started to notice it about 3 days after I installed my new Gavita 1750e. I can’t tell if it’s just light stress or if it’s a PH issue. I didn’t realize I was watering with 5.8 ph water. Any help would be great. New growth looks perfect and new growth looks good, although growth seems slow.
