Is this a calcium deficiency? Or nute burn? Only happening on one of my plants right now. All different strains.

Thanks!!

Mos def burn. Dark green curved leaves say too much nitrogen.

Interesting it's just showing now. I'm 5 weeks into flower, top dressed with gaia green bloom 5 weeks ago, and recently started to water 1/2 strength with a liquid organic bloom nutrient thinking the gaia green must be close to used up. I'll back off on the liquid fertilizer on this girl for a bit.

Thanks everyone, much appreciated

Possibly, but the other plants are all happy and healthy. But could very well be this one requires something more (or less)

PH is the most deceptive biaatch around. It is quite possibly the most common issue.. not even only amongst novice growers!

I gotta admit, I've never actually tested my ph before lol. But I've heard others say the same as you. Where we live now the water comes from a stream on our property, from the mountains. I planted a few outside this summer and they did very well with the water, so that was good enough for my ph test lol. I may buy a tester anyway, it would be nice to know.
Thanks man
