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
Hi, I'm out just now but I'll take a photo when I'm home. No theirs no white fuzz or anything I've looked over them with magnifying glass. Some leaves seem a bit dry tho.
Their in 5 gallon breathable fabric pots with 70/30 coco/perlite
Room temp is about 24 degree c all the time.
the lights are 18 inch from the canopy 18 on 6 off.
I've always watered them twice per day once in the morning and once at night. when I flushed them I gave them half feed for 2 days then 3/4 for 1 day then finally full on the 4rth day.
I cant remember what the run off ppm was I'll water them later and get back to you.
