Hello, thank ya. I try to keep my method really simple, I water them with just enough water so that there is no runoff. I don't worry about hardness, I do use filtered water from the donut shop, pH from there is usually 6.8. I always lower to between 6.3-6.7. I was afraid of stunting or stressing the autos so I tried to defoliate as little as possible. The pots are 3 gallon grow bags, but I messed up at the beginning and all three are 3-4 inches short of soil. I do plan on a plain water flush pretty soon. I'm about halfway through the grow. I did use aggressive LST 2 times a day since day 9.
Sorry for the delay in responding ...not used to the site so it can be some what of a pain ..had to relearn how to play in a modern forum!
On your grow ...If it grows don't fix it !! LOL. .. you're doing great .. " Flush" i would be curious about the runoff ... also how many gallons for each? When growing in coco it was basically feed ,feed, rinse for me but then again they were't auto's either.
