Hello @dedoverde,
Thank you for the kind words and ideas regarding the state of the cannabis plants!
I'm certainly no expert in nutrients, but I just got a ph soil test kit that I'm hoping will be helpful. I'm going to try it out tonight.
My thinking is in line with the fact that I just upgraded my lights and was running full power in a small grow area. After decreasing the light to minimum, the leaves almost immediately went from drooping over, to the nice straight leaves that we like to see :) and the color is going more towards the deep green again.
That indicates too much light was a factor, but doesn't completely rule out some minor nutrient problems as well. Root bounding is likely not an issue, as I just transplanted the bigger one's but some shock could be occurring, especially since the transplanted growing medium is a different soil compound altogether.
I'll be posting about it again within a day or two, maybe even later today, depending on how things go :D
Have a great day!
