I have two plants in happy frog soil Water ph at 6.3 Led full spectrum light 4x4x7 tent Plenty of air circulation and ventilation Have only given one 1/4 strength feed of fox farm plant food Watered regularly. Spots started showing a couple days ago and have gotten worse. I can't figure out the problem. I've inspected for bugs but can't see any
To me ph is low for soil and in soil I'm looking for 6.5 in veg and 6.8 in flower. But I'm not a soil grower... I do see some heat curl on the closeup leaf pics.. The spots to me look like nutrient burn.. What soil did you start with and did it already have nutrients in the soil?? So by you feeding a nutrient rich soil now you're starting to get a salt buildup... How often do you water?
