What is This? End of 7th week of flower

Anybody recognize This?

standard Nute. burn

did you flush going from veg to bud

some shit soils demand it due to their high moss/vermiculite content

or maybe you just gave them too much food?

either way.. either miss a few feeds or pour 3 times the pot volume of air temp ph'ed water

allow to drain in a dim lit place or overnite

to continue in the morning

and then feed 50% less until harvest

good luck

Nute Burns
