i could really use some help with diagnosing a deficiency. about three weeks ago i started to notice little brown patches in the middle of what looked like perfectly healthy leaves and every day it gets steadily worse untill the whole leafs are brown and crispy, i am now worried as they are all starting to show signs if the problem and the 4 plans that was first to show symptoms are looking really rough!
here is what im feeding and info about my crop
strain: blueberry
age: 5 weeks into flower
substrate: coir
ph:5.8
feeding:
canna a&b 38ml per 10ltr
canna boost 30ml per 10ltr
pk13/14 15ml per 10lter
im using a 100ltr reservoir
temp: 78 day 68 night
i flushed it for three days when i first seen the problem, i then thought it might be a phospours problem and hoped theat when i started with the pk that it would help but it didnt and now im stuck!
any advice greatly apprecated
