With heavy nutrient overload , your going to see it in new growth first…

I’ve seen yellow tips on a nute overload but not brown tips like a potassium deficiency only on new growth. Like this one:
Maybe a water to runoff and ppm and ph test is in order @Dickrick527

Yeah, starting to think there’s a ph issue going on. Doesn’t look like zinc but just noticed the yellow veins on the earlier pic which can also indicate a potassium issue. Think something may be locking out potassium which leads back to over nute. She should show her true signs in a few days.

Potassium is responsible for heat management so makes sense.

Well I watered till I got good drainage last night which wasn’t a whole lot of water but enough. Also no ph meter, just tds meter. What can I do what can I do.

I haven’t feed her at all not extra nutes, just what came in the soil.
That’s a really cool chart @Dbpooper. I like how it basically shows that if you lock out a single nutrient, the entire biochemical sequence will be affected.

Exactly what I thought as well, it was posted on another forum I frequent. Really cool as it’s hard to visualize how everything ties together sometimes and what effects what now to remember that on top of what gets locked out at what ph lol…
