Potassium deficient looks like. What is the NPK ratios of what you’re feeding?

I have been using Fox Farm Grow Big, Big Bloom and Tiger Bloom. I have not used very much. I was worried about over feeding.

Are you following the schedule by Fox Farms?

Sorry.

At first I used 1/2 of the amount on the schedule. I read that was a good way to start. Then I stopped when a few leaves started turning yellow. I was worried about nutrient burn.

From looking at your picture I would have guessed a ph issue. How are you measuring ph?
