How is the weight of the pots? not waterlogged?
You can flush easy in coco if needed and just use the basic canna coco A and B, maybe look at foliar spraying with Epsom Salts later...
Are humidity and temps all good?
Lights not too bright or close?
I have a vacation grow method here https://www.rollitup.org/t/ghost-train-haze-the-laziest-indoor-grow-on-earth.1098275/
Better late than never, right?
Can be improvised with cheaper bins etc but works a treat :)
As well as deterioration you must also look for bud rot as the buds get nice and chunky. This can depend on the humidity in your area though.
Nice looking buds :weed:
