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.

Mr Wubstepp i see you have 150 views without any feedback. From the pictures you have provided it seems that you are a terrible grower and should quit imminently. Furthermore you took some pictures with a HPS light indicating you are indeed an idiot and require IQ testing. All plants should be tossed in the trash without harvest. Good day.

first, which strain are you growing out? reason i ask is because strains react differently from certain environmental factors, such as temps, that could naturally bring some of those colors out. here's a healthy plant, that has purple in it's genes and as you can see it's
starting to turn colors naturally.

secondly, you definitely have a cal issue.

what type of medium are you using and what type of readings are you getting from your runoff?

It is an OG kush Humbolt strain. I am unable to read the PH because the meter just stays at 8 whenever I put it in soil and its garbage. ( I bought a 5$ 3 in 1 light/water/ph off ebay from china lol) For the medium i am using BCuzz Hydro mix HP but as i was uninformed at the time i dint put enough in the pot and instead of getting more Bcuzz i added about an inch of Schultz Potting soil because it was nearby.... I would say 90% of it is the Bcuzz though.

I am pretty sure i have both potassium and cal deficiencies. Some leaves have scorched edges that look more like rust indicating calcium. Most of the leaves have yellow scorched edges indicating Potassium. The tops leaves that are pointing upwards and turning necrotic/black indicate really sever potassium from what i have read.

Just invest in a decent ph meter and some calimagic for my next grow and ill be golden....

almost 100% sure calcium overdose causes k(potassium) lockout.

Then I guess nothing left to do but flush flush flush, I harvest in about 2 weeks. Should work well together with the pre harvest flush no? This is my first true grow.


@Unclebuck Pass please :)
