Yellowing veins?

Mr_Maritimestarted grow question 2 years ago

Any idea what could be causing this? The yellowing stems from the veins rather than between. Any picture I find online of something similar 404s. I might have fixed it in my next set of leaves, but still baffled.

It's the beginnings of a phosphorus deficiency.... more PK needed.... But figure out how you got it, first... pH in range (grown in soil, needs to be 6.2-6.5)? Too much iron or zinc? Temps above 15C? Good luck!

Thanks a lot 🙏, I’m in 100% perlite and dropped my ph from ~6.0 to 5.5-5.8, I upped my cal mag, cut out floralicious, and took a break from silica. The new growth looks a little better, but I’m hoping she’s underfed if the ph isn’t the culprit. Lowest my temps get is 68F (20C)

Why are my leaves turning this color?I scratched in 1 TBSP of Down to Earth AP (4-6-2) 5days ago with 2L of pH’d water (6.5). I believe I over watered as the leaves got droopy and then all of a sudden had a bunch of gnats. Killed them, soil is drying but now pale leaves and brown spots
