Ok, I've been battling this issue for months now, and I'm on my second grow where I'm experiencing it. I've done extensive research, and have tried a few remedies to no avail.
The symptoms are that after about the 3rd week of flower (photos below are week 6 of flower), the color of the leaves start fading towards yellow on old and new growth, and old lower fan leaves get VERY yellow and start dropping. Some leaves show speckling or burning symptoms. I run organic living soil that I mixed myself, although on the last grow I had four different types of soil and was experiencing the same symptoms in all pots. I do a VERY light feeding regiment of Big Bloom once a week during flower. I've tried doing a couple feedings of Tiger Bloom in this last run, but it made no noticeable difference.
Strain:
-> Bubblegum
Soil background:
-> Homemade soil: CocoCoir, Peat, EW castings, lavarock/rice hulls, alfalfa meal, kelp meal, crab meal, azomite, rock phosphate
-> Also have had this problem in FFOF new, FFOF on it's second run, and Happy Frog.
Living soil:
-> I have live red wriggler worms that are VERY happy in the pots
-> I've hit it once with compost tea when flipping
-> Aphids are always around to some degree, with lady bugs to combat
-> Lots of spring tail larva in soil
-> Seeing adult sciaridae fungs gnats now
Remedies I have tried:
-> Foliar soluble calcium spray & soil drench @100ppm
-> Foliar soluble magnesium (epsom salts) & soil drench @ 100ppm
-> Repeated use of Big Bloom, with and without homemade cal/mag added
-> A couple waterings of Tiger Bloom
WHAT SUSPECT:
-> Possible Root Aphids, although I haven't been able to find any larva or adults
-> Possible Sciaridae fungus gnat root damage
-> Possible salt nutrient lock out, although I doubt it, given multiple soil types and light feeding.
-> Possible overwatering.
-> Possible that my organic soil hasn't broken down yet, and the plants are literally starving for nutes.
Does anyone have any ideas? I might hit it with some OG Biowar root packs and foliar spray, but I really want to know WHY this is happening. Thank you!
(My homemade soil analysis is below too. This was before plants were transplanted in to it).
