To much or to little?

[Mkenny23]

Long time lerker in need of some of your professional advice got a couple sodk plants in week 7 seem to have some sort of definacey I was thinking nitrogen and maybe potassium tips look burnt and also curling down red purple ish stems on fan leaves and old lower growth going yellow. Using blue planet nutrients been doing about a quarter of recommend dose through whole grow. grown in coco. Looking for advice before I go upping the wrong nutes. Thanks

Purple stems are common on some strains so not to worry.Some lower older leaves will somtimes yellow and dry up due to lack of light so your better off removing bottom foliage that no longer recieves any light.You should be using bloom nutes and cal/mag but i would raise the dose up to at least half or more.

Thanks for the reply I appreciate it. I have been using calmag through whole grow every watering. And in the last watering started with bloom nutes. Thanks again
