White Widow 4 ft tall 3 gallon pot 9 weeks into flower 600w hps Temp: 72-77 during the day, 60-65 at night Hum: 50% Water - 1100ppm, pH:6.3 Organic Soil Mix Nutrients - General Hydroponics: 15ml/gal:Nova Bloom, 2ml/gal:CalMag, 2.5ml/gal hydroplex (used for first time in the beginning of week 9) 1 tsp/gal molasses Same thing happened to my pineapple express that i harvested a few days ago. Spots never spread to buds just fan leaves. I'm thinking maybe magnese deficient but I can't really tell, hopefully someone else has experience with this problem and will be able to give some suggestions. Other than these spots, plant is otherwise perfectly healthy. Pics included, thanks for the help!
