start of p-toxicity? i see bloom-type products in use an dlikely eleveated p/k results, because that's what they are - p and k, typically. dial back a bit. i wouldn't flush or go crazy.. normal procedure if on the schedule, go ahead. when you fertilize adjust your formulat. Reduce the component with P a bit or just take 5-10% off of everythign and see what happens. i have a nute ppm calculator in my main gd profile comment section, if you want.. or find one online. not 100% sure mine accounts for specific gravity or not, but it should... lol.. use one online.. make sure it calculates specific gravity or the calculations are all way off with liquid nutes (labeled as w/v for guaranteed analysis? should be common sense, but w/w or w/v requires it i'm too tired to think out the causality of it).

also, remember this is an educated guess with limited information.. make sure pH is set.. your recent bahriour etc etc... could eliminate what i suggest as a possibility or not.
