Wedding Cake, first indoor grow

This week was a bit stressful. Nothing happened on Sunday, plants looked good. Dark green still but the random yellowing and dying leaves had me puzzled. On Monday I pruned back on the dead leaves. There wasn't a lot, but a little at a time makes a difference and they still need the fan leaves for growing the buds. On Tuesday the girls wanted water. The soil was fairly dry and the pots felt light. I watered with a gallon per plant and did week 8 on the Fox Farms schedule, still following it. A couple of hours after watering them I noticed the top leaves of each plant were clawing a little. This may have already been there, but I just noticed it. With the dark green in the majority of the leaves, a few random leaves dying on a regular basis, and now the clawing. I figured it was Nitrogen Toxicity. I took pics and asked questions here, on week 7's post. It was confirmed that indeed it looked like nitrogen toxicity. I didn't panic, just let the days play out. Wednesday and Thursday I didn't do much. I had run some lines to tie branches too, across the grow lengthwise, so I started doing a few of those. On Friday I finally downloaded an app and paid the $5 extra so I could check the strength of my lights with my phone. It was good on my main tops, but of course lower at the other tops on the branches. I decided to go for it and LST the main stock/tops of all 8 plants. I was very careful to just bow the stock and carefully tie the tops down at approximately the same height at the tops of the branches. Basically, tried to create a SOG of sorts, halfway through flower. See how this turns out. I was able to lower the lights a good 6inches, so that should definitely make a difference. On Saturday, to end the week, they were thirsty again. This time I changed up the nutrients and didn't do it according to the schedule. I cut out the Grow Big completely since it has a lot of nitrogen. I also did 75% Beastie Blooms and 25% Cha Ching, since Cha Ching has a lot of nitrogen as well. Fed them 1 gallon each. And of course, PH'd the water after mixing the nutrients.
