I have been growing for thirty five years in the same location (indoor). About three years ago I got a cut from a well known L.A dispensary. I started noticing strange symptoms I had never seen before (dead areas, mottling patterns, leaf curl, delayed maturation, or more correctly a delayed effect of flowers using up nitrogen left in the leaf) ect. This is a "Virus" period end of debate..! I have a pretty good hepa air filtration but small flying bugs do get in and out it's impossible to stop that completely. I can't say if it's TMV or "hemp virus" or tomato, or cucumber or any of the hundreds of virus's (and more being discovered every year) but it is real and has spread outdoor to my entire foliage surrounding my home. It does not kill the host it only takes it down quality wise a couple of points. from AAA quality to around c+ or B ...and that sucks ASH...! This is real and I believe it's intentional (if you get my meaning).There is work going on now from what I have read (in Europe) to develop resistant strains for breeding to hopefully breed this out of existence for the most part. I believe this will become more of a problem as the years go by and more long term experienced growers are faced with this. I wish nothing but the best for the deniers , hope you don't get it. All the very best people I will not be responding further.The only solution for this is to move away to a new location (that is impossible for us to do unless we win the lotto) Take this as you will.
