Current growing indoor:
Ghost of NYC Fem

Temp and humidity: 75-78°F & 40-50%

Nutrients: Basic Fox Farm trio

It looks to me like it’s possibly a potassium deficiency. I flushed with PH’d water in case it was nutrient lockout. Waiting to give more nutrients. Wanted to see if anyone agrees or if they think it’s something else. Thanks!

Looks like nute deficiency to me. I add cal msg to each feeding starting a week before flowering.
