Here is my OG kush the edges indicate potassium but I am not sure about the necrotic black/purple patches. Is that just what it looks like after sever potassium issues? I know phosphorous will give you pruple blotches but this look a bit different.
So the story is as follows. About two weeks ago i thought it was a cal/mag problem so i treated as such.I did not have any cal/mag but i just loaded up the on the BIG BUD which has a npk of 0-1-3. I then thought my soil ph may have been to low. I did not have a way of checking it. Last night I added a 2l bottle of water with a bunch of baking powder, woke up noticed my plants seemed worse then finally realized my problem this whole time was potassium. I am not sure why since i know it is in the soil with all the chemical nutes i have been feeding them. It must be due to a salt build up or bad ph right?
Anyways It has been 7 weeks exactly I plan to harvest in a week in a half to two weeks so i doubt I'm going to do much to fix the plant. The good thing i guess is bud development seems to only be mildly affected by potassium issues. This thread may be pointless other then to verify what it is and help others.
