5th Week Flowering Plant dying!

Looking over your diary and previous question it seem the last one was where you where told this is a Calcium issue. I'd recommend picking answers to your old questions to close them out. The affected leaves will not get better and it will only appear to be working on the unaffected leaves by preventing them from decaying and the others ones from decaying more. If the yellowing/brown spotting has as not spread, then that is the full extent of the fix your going to get. Your diary lists you are PHing your water down to 6, this is a bit low for soil based amendment grows. The low PH harms the natural soil microbe life and allows some of the opportunistic ones to take hold in higher populations. I aim got 6.5-6.8 and it has served me well though all my soil grows. Given this is so late in its life. Stop giving it more nutrients from dr.earth, they will not be broken down in time for the plant to use before it dies. Dry amendments take about a week to be broken down and last for about 2 weeks after that. in total 3 weeks to a month ish. If this was my plant, just give water, don't PH it for the next week. Worry about PHing it down to 6.5-6.8 on the following week. If you wanted to you can also give it a bit of molasses to help boost up the soil microbe life. I do about 1tsp 5ml per 4L. less is more. Can continue to use this until the last week in flower before you chop. No idea how your watering but try not to get any runoff when you water unless their is signs of lock out and the plant is getting burnt from the excess feeding. Best Of Luck!
