Good morning Hammer,
I believe this is a continuation from our other thread about those unknown brown spots/ necrotic tips etc., these come in flushes and I believe it’s pH related ?
The thing here is these are all clones from the same mother son will have this to varying degrees and some will not.
I have four cheese clones (stinky!) that I just put into flower, two have spotting to some degree, one has these few little Speckles on several lower leaves and another one has nothing at all
I’m watching them now that I have my new pH meter to see if the one with nothing develops these as well. These spots magnified are small irregular shaped spots and not round at all, and they’re only on the veins
I bought a new pH meter Sat. and I’m going to see if this continues. There’s no mites. I’ve scoped my plants up and down, front and back overnight and not one, I’ve had mites before, sadly I know how to find them
…and no Miracle Grow ! …my high temp hit 88 for a few hours when I stayed late one day at the beach, I’m guessing it was substantially higher at plants tops to cause that heat stress but besides that it is always 78 - 82 degrees
