what is your soil mix?
if you just needed to start fertilizing at week 6 of flowering it must be some hell of a hot mix already.

lol yea its strong shit, the new seedlings burn a little in my soil the 1st few week of life...

its just good basket compost from the local garden centre, full ov everything long lasting..

im going to just water for a few days now, and see if the burning dies down a bit..

if it dosent then i obviously will no that its light burn!!

nute burn usually show only at the tips at first.
light burn usually burn the leaf equaly.
