I've 2 bubba ks and 2 Granddaddy Purples. They are at 5 to 6 weeks. 1 of each has been steadly yellowing. I know this can be normal. But could yellowing be brought on by an excess of P&K relative to N? I use earth juice bloom and grow at 1 to 1 (plus catalyst,meta k, microblast,Hi Brix.) until flower then step up the bloom considerably over the flowering period keeping everything else at constant ratios. I've been reluctant to increase the grow at the same time but am thinking maybe that was a mistake for these 2 girls.
