After spraying with sodium free sparkling water this happened. I searched all over and cant find anyone who's ever had this happen, is it from something else? And how can I treat this problem? It's probably halfway through flower

looks like you have a P deficiency. have you been feeding it nutrients? if so, you probably have too much nitrogen in it rather than phosporous. maybe the sodium free sparking water is too high in pH as well. check to make sure its around 6.5

yes, Big Bloom at like 3/4 strength...I am using a shallow water culture,the Ph bounces all over the place. Never checked Ph of the sparkling water, just cant believe it would wreck the leaves like that

Damn, thats weird. From what I've read and experienced it looks like a potassium(K) deficiency, especially because of the red stems. Another possibility would be leaf septoria, a plant disease, its not very common indoors. I'm willing to bet it's K deficiency. Do you know your ph level? Are you using a bloom booster? A bloom booster usually contains a lot of potassium(K). I'd try that if you already haven't.

Is there anything I can add to the solution to fix the P? Actually I lost my Ph kit somehow like 4 days ago, gonna pick up a new 1 2day. But I try to keep it between 5.8-6.5. First grow ever but been reading and researching/planning for about 5 years now HAHA. so i guess this is stuff ya learn "on the job"

Well you should get that Ph in check because that's what enables your plant to absorb nutrients. You're bloom booster should have kept this from happening. So it's probably just your Ph, which needs to be 6.0-6.5, that's what I've been taught.
