Hey guys. In my fifth week of flower and I noticed some spots on one of my plants. I'm growing in biobizz light mix and feeding them every watering, about once every three days, with canna nutes(Ec 1.5). It would be great if someone could tell me what they think it is. The most important thing for me right now is knowing if it's a deficiency or burn so I can know if I should step up the nutes or give em plain water. Thanks
