I have several plants growing under LED spot lights. Not my first grow. Problem is one plant just up and died and I am clueless on why. I was using white vinegar to lower the PH from around 8 to 6.5. approx 5mil per gallon works well. I was using vinegar for a few months. I read about molasses and changed to using Molasses because it fits into my grow system much better. I grow totally organic. PPM is around 125 before adding molasses. I add 40 mil of diluted mix of mollasess and ro water to a gallon and the PH is 6.4 -6.5. I watered my plants once with the mollasess and two days later one started to wilt. I figured it was from dehydration. Watered again with molasses and plant got worse and died. No other plants show any signs of problems. all plants are treated exactly the same. Im figuring something in the root zone but I dont know. Any input is greatly appreciated.
