Autoflowers

Left for work for the week. Wasn't able to water or do anything with them til I got back on Friday day 39. But I'm amazed at the growth! Practically one foot in growth! 5 days without water wasn't too hard on them. Still showing some signs of potass/calcium defiencies. Day 35: ... Day 36: ... Day 37: ... Day 38: ... Day 39: returned from work. Watered with nutrients. Raised light....while I was gone the plants grew to within 4 inches or so from light. Day 40: flushed partially Day 41: flushed with hose outside until ppm run off read ~200ppm. It took ALOT of water (probably about 20 gallons each plant) to get ppm down from a starting point of 2500. I'll need to do better with reading ph and ppm levels of run off every time I water
