Should i worry? Other growers said this is most likely a potassium shortage yesterday so I started feeding her a little more but if I compare todays pics to the pics of a few days ago I'm kinda shocked. You'll see which are the pics of today
Big older leaves normally die off. If you really want to know what is going on, high, low nutes, then check your runoff ph and ec levels. That will tell you if your low or high on nutes and ph. Cheers
