using a 1k watt hps and am currently 5 weeks into having yellowing and droopy curling issues, I feed once a day with 6.0 ph after 3 hours in a bubbler, im using coco and canna nutes, thinking it might be a ph lockout please tell me what you think.
I Fed with 5.7 ph'd epsom salt water, how long does it usually take to absorb and start recovering?
