3 RQS Autos (First grow)

This week has had a good amount of growth, especially the Northern Light plant. I've decided to forego any more BS attempts at LST and just let the plants do their thing for the remainder of their grow. The incident with the Bubble Kush from a few days ago hasn't seemed to slow anything down at all. The section where the main stem snapped and was taped is looking alright. I didn't manage to get a pic of the recovering break because I don't want to risk making the damage worse by trying to pry stems out of the way to get a pic :) The Northern Light is showing some early signs of flowering, same with the Bubble Kush. I've not seen any on the Sweet Skunk though. All plants are showing some nutrient issue or another. All of them, I think, show an excess of Nitrogen, I have not given any veg nutrient since that very small amount last time. I think I goofed though and gave them too much. I'm sure they will be alright though. Since then it's just been pH adjusted water and some great white. There is some copper discolouration on some of the lower leaves of all 3 of the plants, along with purple appearing on an increasing number of stems. The Northern Light, especially, is looking very dark green, almost blue. Phosphorous deficiency maybe? I'm going to start them all on bloom nutrients in the next few days. EDIT: All plants showing signs of flowering and have been moved onto bloom nutrients. Some last-minute defoliation and very minor LST was done for airflow reasons. I know that it isn't really advisable to defoliate an Auto at this point, but there was no choice. The kush and skunk were unmanageable without removing some of the fan leaves. It wasn't major defoliation though, so I am hoping that the recovery time required will be minimal.
