Unsure of what this might be?

Hi guys, I've been having some issues with this plant in particular, the strain is jungle wreck.
Is this nutrient burn or just a sulfur/potassium issue? I first flushed the soil when I saw signs of this problem arising, just to see if it was nutrient burn but this problem is pretty much all over the plant now. Have tried feeding some nutrients (a mix of micro, grow and a tiny drop of bloom for sulfur) and whilst new growth seems nice and green quite a fair amount of stems on the plant have turned purple (I've checked, it's not genetic). Perhaps one of you guys could bring some light on the issue? Thanks. (Pics attached)

What's the deal on the soil? What are you using? Like most everything. It's PH. Something is locked up. If you haven't been adding a bunch of stuff. Using a really low ph water.

Then the next on the list is soil. It's not stable.

try a proven nutrient line, I suggest botanicare, and follow the directions on the package. no need to add anything but water. my ph pen's been on the shelf for years and years unused. One bud from one branch from one plant will pay for a gallon of the stuff, lasts months and months and months.

Can't remember the brand but it was PH 6 and had added John Innes. Had a successful grow using this soil prior using the same stuff. Okay so just ran some tap water through the soil and the run off is at PH 6.0, I could try flushing the soil again but I don't know if there's even any salt build up in there. I flushed the plant around a month ago until the runoff was at the same ppm reading as my tap water (40 ppm's).

Chemphlegm - Cool man, well I was thinking of changing nutrient line after I've ran out of my current one. They're synthetic nutrients so it's super easy to burn the plant unfortunately.

Everything I've researched. The soil ph runs at 7.0 for cannabis. Not 6.5 or lower.

6PH is hydro level. Not in soil.

My solution is at PH 6.8 when I water the plants with it, I guess maybe my soil PH is low, it's mixed information on google regarding what PH magnesium and potassium can be absorbed at but generally it looks like anywhere from 6.0-7.0. Found this, there's a few of these about.

I can't attest to that chart. Never seen or read that before. Personally there's no way I'd go that low. I water my plants with non adjusted water. Soft water. I've never had the lock out problems. I believe it's over thinking it.

If your plant was outside. You can't ph the rain. Next time it rains, see what the ph is. Test it. If it's 6.0-5.5 low, it's eating holes in your car paint.

Same here, the solution drops the PH ever so slightly from phosphorus content really. Not had issues up until late, the plant is either root bound or like you say it could be a lockout. Perhaps from salt. Doing a good flush and mixing fresh nutrients to be within the 6.5-7.0 range.

Potassium deficiency due to overwatering and/or Nitrogen toxicity

There's a slight joke going around and it's sobering. I watch every now and then. Helps keep me sane in the modern age of cannabis. I hope you enjoy it. It comes with respect.

Thanks man, I'll try feed a little lighter. Nitrogen is 6% in my micro nutrients.
