Not super happy with plant four, still a little pale in color and some of the leaves are drooping. I'm thinking it may still be bouncing back from nutrient burn. Also a bunch of the pistols are turning Amber which I also believe may have to do with nutrient burn from too high of VPD. I'm gonna let plant for dry out one more day and feed tomorrow. Hopefully the leaves start pointing up!
Thanks @James, looks like I have a little unexpected experiment going. I thought I had 4 autos in the tent. Turns out 2 of these gals were photos which I discovered on week 6 when 2 of the plants were not flowering on a 20/4 light schedule. I switched to 12n12 and the other 2 started to flower. I did not top or train these 2 as I would typically with photos, also I had my lights on 10 while they were still in veg. Looks like they are doing well but I am curious to see how much these produce in the end. The wedding cake autos looks nice and are a week away from done at week 7. Best of luck to you as well!
