AMS Potatoes under Mars Hydro #1

Day 57. Not a happy camper, but she grows, still fades tho. A bit confused what is stressing her. I cant give good air circulation, think this and too intense ligh caused her unhappiness. Mars TS1000 is dimmed to 80% , quantum board on 60% output. I know she wont get green, but hopefully sugar leaves manage to stay healthy, which they are at the moment. Otherwise its a pitty harvest from such big plant. Not first run with that strain, always picky, but grows big ;) maybe with last bean ill crack her style, saving it for future ;) Tomorrow watering day, still plain water. Happy Growing !!!
