I get those red stems all the time. It's common with GG4 clone only.

Me too with certain plants. They can be green with proper balance. Usually an excess of a macro nutrient)s) when seen early.

It's probably partially lack of P. I've grown it before without the purpling.

Well I got the plant healthy again but chopped it down to make room for some other stuff. I did figure out what that deficiency was though so something was learned from keeping it around.
For everyone that said Zinc Deficiency you earned a Gold Star. The reason the zinc sulfate wasn't working is because it takes a long time for it to be useful I found out after some reading. I cheated by using GH Flora Micro which has zinc edta which is available immediately and problem solved. I had another GG4 starting to do that and fixed it with just a little Micro so that confirms it is a micronutrient and zinc would make sense.

I guess it could also be Manganese deficiency since the symptoms look about the same on the pics I've seen. It's definitely one of those 2 since I know it's a micronutrient. I still think it's zinc but I'll try to narrow it down if I can.

Would be interesting to see a soil test on your 5 year old mix.

It would. The only problem is all my pots are slightly different since they've all had different amounts of everything. I am planning on getting some tested one of these days though.
