Here they are on the plant:

Everything has lead me to believe that these are PH spots as a result of nute lockout, but I'd like a second opinion from you all. How would one treat the plants? They are flowering well, but I'm afraid that if this continues I will no longer have any fan leaves to supply my meds with their food.

Thanks for the help.

Looks like nitrogen and manganese deficiency. Though as you say it might be nute lockout due to wrong pH. Do your nutes include manganese? I've noticed that a few nutes on the market doesn't include manganese. If it don't, do get some nurition that has manganese. Else buy a cheap pH-test and see if that's the problem.

You buried burlap bags full of soiless mix? When? What did you put them in? Just a hole in the ground? No prep?

 

[Cerb]

Yes, the bags were filled with LC's soiless and were hit with liquid karma as per the instructions regarding the mix. The holes were dug and the sacks were dropped in. Have I committed some sort of outdoor growing crime that I'm not aware of?

This is my first outdoor grow, so if I fucked up I'm not surprised.

I'd lean towards high humidity helping set up botrytis (bud rot). Looks an awful lot like what I got going on in my patch.

You should have prepared the hole. Dug it 3X the width of the rootball and amended it.

I don't know what to say. You may have rotted your roots if the water pools in the hole. It may not be getting enough nutes from your mix. It could be a lot of things...ph...?
