hey fellas, i got a lil issue i searched the forums for info but found nothing on my problem. i have 4 GDP's on a 4x4 scrog. plants are in 5 gallon felt pots and have been fed nothing but organics their whole life. I.E bat, worm and seabird guano molasses and roots organic trinity for trace elements. brew all this in teas and this is what the get watered with. feeding schedule is feed, feed, feed ,water repeat. i am % weeks into flower with ^ to & weeks to go and i have been getting these balck spots on my fan leaves. the leaves get crispy and then curl up. there are also alot of leave with tiny yellow tips. no all 4 plants have been fed the same thing but so far only one is showing issues. i have a certain amount of yellowing but thats natural 5 weeks into flowering. i mean correct me if im wrong please. but take a look at my pics and see what you guys think. thanks.
