@Pedman Welcome to AFN OF is not going to sustain the entire grow unless you are in a large pot which does not look to be the case. You may have also washed out all of the soluble nutrients with that much rain. recommends Big Bloom to start but I think you will need a full balance fertilizer with all of that rain.

I neglected to add that the plant is under a cover to keep rain away from the pot. Only one out of 4 different strains that has any symptoms.
