The experiment continues. I'm away for the first 30 days of this grow and am automating the grow by using the Blumat watering system along with the automated fan from AC Infinity. Let's see if I succeed.
Day 24 - This image from the camera in the tent show good progress. The temp is stable but humidity increased a little.
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.
