Second solution change. Filled buckets the day before to allow water to stabilize and reach room temp before adding nutrients and adjusting pH. The pH stabilized last week at around 6.3. Starting a bit lower at 5.7 so if it inches up I shouldn't have to adjust to stay in range. Both plants are looking strong and growing fast. Waiting for my LST clips to arrive, I'll prolly start LST sometime later in this week or early in the next. Not going to do any pruning of these girls just LST.
