Is this a Nitro surplus?

Rookie grower here. Gave this plant a 5-10-10 feeding with organic fertilizer. Started to get “claw” leaves and brown spots. Any info on how to correct? Flushed with about 15 gallons of water already to try to reset nutrients.

looks like too much nutrients or salt build up which is locking out potassium uptake..i just found this .
When soil salinity is high (from excess fertilizer or sodium in the water source), potassium becomes unavailable for root absorption, causing deficiency. Cold soil temperature also causes reduced absorption. Conversely, potassium can build up in soils that have had excessive fertilizer applications. An excess of potassium is difficult to diagnose if other nutrient imbalances are also present.
I am very wary of curling leaves now as i have killed , well not killed stunted, locked out 2 grows from too much nutes or a build up from not flushing. you can give lower ph water for a while .my other plants that are in full sun dont curl up
5;10;10 seems a bit high for veg , mine went haywire when i gave it 14/15 pk half way through flower. while the roots are recovering and drying out you can always foliar feed

Thanks man! They seem to be recovering after I flushed yesterday. Healthy leaves are perky again and no more curling. Still look a bit scraggly from the shock, but I'm optimistic. Going to take your suggestion and cut back nutrients for a few watering cycles and feed again week 4.

Sounds like a good plan. Nicely done.
