First time trying 10 gallon pots so don't know. 5 gallons they started suffering around mid flower week 7. Mind I did not add lime and lockout was the main culprit. My well water is 5.5 so I use water from the creek behind my house which is 7.7 to get to 6.0. I go to 6.5 during flower but was a little late or lazy in doing so last run and it showed. Lessons learned. Still at respectable crop. I believe my compost helped a good bit. I do plant my seeds directly into the mgo so it isn't too hot. My goal is to get where they are water only. And we are talking autos. Never did a photo indoors but have some good genetics that I learned don't do well outdoors here so maybe next winter.
