I did the Flushing for all of my plants and stop adding the nutrients this week, prepare for the flowering formula nutrients next week.
Also I dimed the LED Grow light to 50% (around 200w+) to make each branches get taller so they have more space for the flower to grow on the spot.
@Cheesebearger, the drooping leaves, discoloration and bushy way its growing is a warning. You have to leave it and hope it gets better. Let the soil go dry on top. I hope it pulls through for you.
@NexusDevil, Thank for the recommendation, I planned to do the Scrog later, that's why I'm trying bend down the bigger plants on the left side to make its height the same as the others in the right side.
I brought the seeds from the Linda's, It's the same strains but I guessed the genetic didn't quite stable at all.
