Pics was taken after "light flush" coz i cant do proper ( i'v in guerilla grow) so i flush 18l pots with 10l of 6.0 water.. my runoff was about the same (6.2ph).., I must say that in the begining i didnt have ph tester so ph was accurate only last 2 watering, some people told me that i owerwather them and its ph lock because of to mush salt.. this simptoms happned after my first fertilaze with hesi start kit 8i went full dosages).. and i alwas left my runoff water to plants drink after watering them..so some people told me that is mistake..
