This isn't only the bottom growth, the leaf in the picture is prob from the middle to top area of the plant
Are they getting cal/mag?
They don't typically get it but i did give it last watering because i thought it might be something along those lines. I've been growing this strain a long time and haven't really ever needed to use it before.
same soil? that's what it looks like though.
Yup same soil
My only problem with that is that it was more of a blotch then little brown rust spots. Would this mean its different or just more of an advanced case?the top is cal def the bottom is mag def
I recon backtracker has nailed it. No its not advanced but you want to get on top of it before it does become advanced.
what is your soil like? those pots look small for plants that big they may need water more often. when leaves do that it's usually something to do with the roots. do you have a moisture meter? you can tell for sure and make sure the water isn't running down the side between the pot and soil also a wetting agent like yucca will let the soil absorb water easier and it's good for stress too.
5 gallon planters and yea i know its been weird lately they've been wet for much longer than usual (almost always dry before 3 days lately its been 4+) . I don't use a moisture meter i can tell with finger/lifting the pot
