I have a GG auto that is the biggest of all my plants whose fan leaves have been first getting speckled then losing green and then yellowing.
What seemed really unusual was how most of the upper leaves were passed over only to have one of the top fan/cola leaves yellow.
This is the end of week 5 of flowering.
I added a full dose of FF bush dr. a few days ago and it seemed to be working for a couple days but seemingly overnight more yellowing occurred.
Not sure if it’s bc this plant has a greater demand for nutes and i’m not giving it enough or something else is going on?
It’s been pretty hot the past few days but they’ve been well hydrated throughout.
I have been spraying daily with a soap nut solution to prevent infestations.
Please offer any assistance if you can
