Stardawg photoperiod Whoops!!!

Ya flowering will happen if you have your light cycle on 12 hours of light and 12 of total darkness. If you have any light leaks it will fuck your plant up. So make sure dark means dark in your space. It can take till the end of week 3 to see signs of flower. Looking at your pictures it looks like you are on the brink of problems. In fact there is already problems, they just aren't blatantly obvious yet. My advice would be to flush that soil out with lots of 6.2 pH room temperature tap water. Flush out salt build up over the course of your veg growth. Let the soil dry out, then resume flowering feed regiment. And maintain a 6.2 pH
