Lime Green Woes

Trying to diagnose an issue with my plant. Getting some lime green / yellowish on new growth transitioning downwards in the middle of the plant.
Soil is FFOF with extra perlite. FF trio bottled nutes at 1/3rd chart recommendation with 5ml/g calmag every other water. Water ph.d between 6.2-6.5 Also use recharge once every 2 weeks or so. Week 2 12/12. I'm thinking it's either a sulfur deficiency or potassium excess. Leaning toward sulfur due to some purple streaking on stems which is visible in picture. Any advice? Was considering top dressing gypsum and cutting out cal-mag for a while.

That lime green color is pretty common in new growth, especially if the plant is growing fast. As long as the leaves green up by the time they get full size, it's fine. I wouldn't change anything unless you see other signs of deficiency, your older leaves look good.

Try bumping your feed to at least half strength. And why so much cal mag? There's no excesses observed. Forget the top dressing and bump up feed strength.

Very very slight hint of tip burn, hard to imagine it being a deficiency...but it's not a small plant anymore, she's eating.
And i see splotches of the light green you mentioned throughout the plant.
I like ur sulphur diagnosis, you could try a crushed garlic foliar spray. 24hrs later she looks different, then ur onto something.
