Hi, I'm currently on my first grow and loving it. I've got a few autoflowers 9 weeks in. Last week they had nitrogen toxicity so I flushed them with ph water. Now some leaves mainly at the top are turning yellow and brown. I feed them flora series, calmag every day at the recommended dose. Once a week I give them seaweed extract and also big bud at 2ml per litre for week 2-4. My run off is always about 6ph as is the water I feed them with, their grown in coco coir, roughly 970ppm which is a bit low as I've read it's to be 1000 but I'm using florals feed chart. Lights 18 on 6 off. Not all my plants have this soo I'm really puzzled. Any help would be greatly appreciated. Thanks
