Usually when I see purple stems it’s a calmag issue. What kind of medium do you use again? It’s early I haven’t had any coffee yet lol

Have you checked the temperature at the root zone to see if that could be the problem

Magnesium Sulfate will have your iron micro nutrient in it with many other micro nutrients to complete the chain of food cannabis needs. I don’t know if you are supplementing any epsom salt but wouldn’t hurt to add a 1/2 teaspoon in the gallon and wait to see if those spots stop and are not on new growth. happy growin hoppie !

I personally think that’s the beginning of a calcium or phosphorous deficiency judging by the one that you labeled “worse off”
If you grew with bottled nutrients them I would have plenty of suggestions for you but I’m new to this organic stuff myself.
Let’s see if @organicgrower4m or @Ladithief got some ideas
Magnesium deficiencies usually have interveinal chlorosis associated with them. Chlorosis is just a fancy word for yellowing

I’m using general organics cal mag I’m running 100% organics ATM. Already treated for mag def and iron def I have separate products for both and zinc as well they all have similar functionality so I find it hard to separate them or isolate the def often

No interveinal yellowing just around spots

Exactly, which leads me to believe it’s something other than magnesium
