Hello all. This is my first grow. I am 5 weeks into flower, and this started happening to 3 of my plants.
2 Blueberry and one Super Lemon Haze.
I have been using 4mg of calmag per gallon every time i water, with GH Floragrow fertilizer once a week. They are all in 3 gal fabric pots. My temp stays 80 day, and low 74 at night right now.
Thanks for your help in advance!
