Ya I have been adding more and more chicken manure to my soil mixes and seeing continual improvement with early fading. They are definitely hungrier.
Could be aeration as well. Although i agree, could be linked to nitrogen..
I always assumed most organic soils should be good on nitrogen, especially from all the worm shit and kelp.
My current batch is definitely fading early.
I checked a couple plants roots after they finished and was surprised to find weird root bound with some dry spots.
Next recycled batch is loaded with vermiculite/perlite and rice hulls. And a half cup extra* of everything else i usually put in, kelp, crab, fish, oyster, gypsum, and couple more for glacial rock. Also decided to put in a little Jamaican and Indonesian bat guano, half cup each. I know more doesn't mean better, but i hope it does in this case.
Also, although i suspect my current batch to be lacking aeration, half my plants are doing very well, especially for being 4-5 weeks in flowering, however, looks to be lacking yield.
Not sure if its genetics, or maybe organic matter isnt avaiable yet, that is why I have been increasing enzyme feedings with em1, coco and sst. Hopefully humus matter can increase and solve the problem of early fade.
Was planning on starting a thread in the organic section on solving this problem.. But it would make more sense too talk about it here, cobs can be making the plants act strange.. Could also be geo engineering, or finckle matter in the air....
