Leaf Edge Browning/Yellowing

I have a number of outdoor plants but one of them has a problem. I hope someone here can identify the issue. Picture attached

Seems Potassium deficiency. It could be a PH issue locking out nutrients.

An overall picture of the plant and filling the following support ticket would allow expert growers to help you better.

I find it odd that out of 6 plants this is the only one with the issue. I am using the same seed, same soil, same feeding, same water, same everything.

I should add this is an outdoor grow in Southern California. Daytimes about 80-85 and nights 60-65. We typically have low humidity in Los Angles. There is plenty of outdoor breeze. Once again, out of six plants this is the only one exhibiting this issue. I looked for bugs but found nothing. As the plants are large and touching one another, if I had a bug issue i would suspect it would be on all the plants.

Can this browning be from too much nutrients added during watering? I’m using Fox Farm Big Bloom

I am not an expert. I assure you it is not a bug problem. But I would suggest you to fill that support ticket. And if they are in pots to run a PH run off test and TDS/PPM test.

Could be, do you have a ppm going in?

Not if you’re only using big bloom. There’s not much in it. It’s the micro nutrient line for fox farms.
