anyone ever had problems w/ connoisseur?

i have had the hardest time adjusting to using AN connoisseur as i was using all fox farm stuff before. i am really hoping that this will not turn into a AN bash fest. i figure there must be people here that use AN stuff and could help me. i am in dirt not hydro and i can't seem to find the right dosage. i am using it at 1/4 of the light feeding schedual at first then @ 1/2 but i still get tip burn and lose color on the fan leafs after about week 3 or 4 of flowering. i flush every couple of weeks (after the second feeding). has anyone else had problems using conn. in dirt?

having the same prob with iguana juice. 7oo ppm and its burnin up. yellow by week 5

yup that's about the ppm i am at usually, probably a little lower at first. i don't understand why this would happen if properly flushed regularly and such a low ppm for a plant that is about 4ft tall and decent foliage.

i thought that iguana j. was not a chem fert but an organic fert, it shouldn't burn right?
