Having some problems with this one lately. While her sister plant is looking perfect, this one has started to show some deficiencies while also significantly decreasing its water uptake. As well, while the other pot feels completely soaked, this one feels almost dry to the touch. Yesterday, I added some pH down to bring the pH from a relatively high upper 7s back down to a low 6. I also did some foliar feeding with a mixture of Big Bloom, Grow Big and CalMag. This morning, the leaves looked in similar condition however the pot was still dry. So I did a flush of the self-watering base making sure to scrub out all and any salts that had dried and collected. I then refilled with tap water. Once I’d got the plant set back up, I then watered it from the top with a similar nutrient mix as before, about half a gallon, just so the the soil was wet again. I’m rather confused on why this is happening when its mate that has been experiencing the exact same conditions, feeding schedule, etc. is doing so well. I will continue to monitor closely and if necessary pose a grow question.

Happy growing and good luck buddy ☘️
