Northern lights auto 2nd attempt

Day 44: What a week.... I've finally figured out for sure what my problems been with Samus or at least I've eliminated any other causes. The soil pH was sitting around 4 with the other girls coming in around 5. I've got a pH meter ordered to dial it in accurately. I gave all 3 a heavy flush and will adjust the feeding once the pH up & down arrive on Friday. This was super frustrating but interesting to hunt down and diagnose but it'll be something to watch out for/mitigate with the TD grow Day 48 - After much testing I've worked out that I screwed the pooch with the flush as my water supply is slightly alkaline. The Canna nutes take my water to about pH 5.5 anyway so I took it down to pH 4.8 with some heavy diluted pH down added a drop at a time to offset the girls sitting in alkali water.
