showing signs of a magnesium deficiency is my gues...

ok what I did so far and will continue to do since this one is a experiment, the plant was vegged the first time for 6 weeks, was put in to flower for two weeks, sprayed one branch with silver thisolate spray, ending up re vegging the plant with that last branch that was about 6 inches tall, turned that into this plant that has sat in veg for 13 weeks is now back in flower. I have used Epson salts and a bloom fertilizer new growth seems to returning, I have also have her another hair cut and removed a lot of the eye sore leaves. I will continue to spray the one branch with silver thisolate for the next few weeks to see if I got the mix right, the branch has not been showing signs of that burn. now I am thinking that this plant had a magnesium deficiency that I should have fixed before going back to flower. I also think that the plant has received loads of stress and with the spraying with the strong solution the first time, going in to flower then re vegged then going back to getting sprayed, getting a magnesium deficiency and going in to flower and getting re sprayed. I am interested in seeing how far I can push these plants. this plant has a flowering time of 49 days. so I will keep her going but I don't think ill smoke the bud from this plant just to be on the safe side. just want to trying to get seed. Yes @DoktorHolland I use nitrogen during veg, but reduce that in flower, as the buds form much better with lower nitrogen during flower. When I put the plant in flower I will use a low dose of nitrogen nutrient, but get rid of that at the end of week two. then low doses of it, by the end of the fourth week of flower I get rid of nitrogen all the way to the end and then a good 3 week flush with cold water to shock the roots for trichome production as well as great fading colors.
