hey all, how would you handle a situation in which your plants are nitrogen deprived but nute burned? All I have is fox farms trio and calmag plus, I dont want to add any of the tiger bloom which has the most nitrogen because i believe that to be the source of the burn, im at a loss here - growing in FFOF plants are autos that are about 3 weeks into flower - i do have the grow big though which is a 6-4-4 but ive seen people say to not use the grow big during flower?
