Using 65-100 gal soil pots outdoors under greenhouses. Decent sun but far from full sun. Supplemental lighting. Empire builder soil (high quality). GH flora series expert line of nutes. Feeding every other watering. Watering close to every other day. Always checking PH with Hanna Combo pen. Sprayed with flying skull nuke em quite often, but always as directed, in the evening after sun goes down and lights are off. Seeing some extremely burned leaves on several plants in random areas of the garden, with almost no warning signs ahead of time, seemingly came out of nowhere. Some leaves have had that burnt edges look but some of them just straight up fried. Some stems looks almost diseased. Affected plants are not drooping. Rest of garden looks very happy. My only thought is that the soil has an abundance of one nutrient that we are also feeding it, and that nutrient has become over abundant in the soil. Checked the ph of the soil today and it was 6.3/6.4 in pots of affected plants and non affected plants. Our ppm's on our feeds have been consistently around 800 lately, and definitely have not risen above 1500. Our feed during veg was a little bit higher of a number than it is now. Any ideas IC? If not nutrient burn then I'm stumped.
