Silver Surfer Haze

Just transplanted to a new 10L pot. As I had to wait for the pots to arrive and to have space cleared for them, I had delayed the transplant a bit, and my bet is that is the probably cause of lower leaves showing some signals, I was afraid root could be in bad shape but they were great as seen in the picture. If I had the space, I would transplant them straight to 50 L pots, it will be their final destination, but as the flower tent is busy and there's not enough space for 50L on the veg for now, they will have to be transplanted again later. Actually using 2 65w (totaling 130w) but I will upgrade it soon
