Started out with 5 seedlings and this is the only one that came out looking like this. It’s is about 4 weeks behind the others.
Yeah that advanced nute burn ...way too much nutes it real tough to do anything ..but a flush may work pour 3 times the pot volume thru the pot with air temp ph'ed water do it days end so they drip out over night to continue in the morning no further nutes required you are toxic good luck
Isn’t it weird that it started when I transplanted it from a seedling and all the way through to flower. Same medium & same nutrients .
