Day 78 - Fading nicely and the Colas are continuing to stack. Trichomes are still clear so I wait.
Day 80 - Trichomes on the smaller plant are starting to cloud with a few turning amber. It won't be long now.
My two Grandaddy Purple Autos are light green/yellow in color. Is a lack of nitrogen the cause or is it something else? What do you recommend to fix the issue?
Light is too close too soon. Apparently the others did not take the time to look. You got light stress. Should be at 14 to 16 inches in heavy flowering.
